CAS No. 3319-31-1 The **analysis of TOTM** **(tris(2-ethylhexyl) trimellitate)** and the quantification of its [degradation](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/laboratory-for-the-analysis-of-thermal-degradation-of-polymeric-materials.md) products are essential for monitoring its behavior within the [polymer](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory.md) matrix and controlling its role as a high-performance plasticizer. This approach allows for monitoring its stability, anticipating its aging, and evaluating the overall evolution of the polymer or the formulation in which it is incorporated, particularly in applications exposed to high temperatures or stresses. The objective of this analytical strategy is threefold: Durability guarantee - Ensuring the long-term stability of plastic materials or finished products formulated with TOTM, known for its low volatility and thermal resistance. - Preventing premature deterioration phenomena such as hardening, loss of flexibility, or excessive migration of the plasticizer. Mastering quality and performance - Maintain the overall effectiveness of the additive system (other [plasticizers](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/plasticizer-migration-study.md), stabilizers, process agents, etc.). - Avoid formulation imbalances by closely monitoring residual levels and derivatives resulting from TOTM degradation, particularly in materials subjected to harsh conditions. Regulatory compliance - Strictly control the concentrations of TOTM and degradation products, particularly in sectors where migration and chemical safety are strictly regulated (medical, cosmetics, technical devices, packaging). - Ensure compliance with applicable standards and limit values ​​specific to each area of ​​use. ### What is TOTM (trimellitate) CAS No. 3319-31-1? **TOTM (tris(2-ethylhexyl) trimellitate)**, CAS 3319-31-1, is a high-performance plasticizer used to provide excellent thermal stability, low volatility, and very good resistance to migration in plastic materials, particularly flexible PVC. Thanks to its trimellitate structure, it is preferred in applications subjected to high temperatures or requiring significant durability, such as in the medical, automotive, and certain technical wiring sectors. It is a plasticizer of choice when longevity, stable mechanical properties, and strict conformity are required. ### Our organic additive analysis services [Analysis of Irgafos 168 (CAS No. 31570-04-4)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-irgafos-168.md) [Analysis of Triphenyl phosphite (TPP) CAS No. 101-02-0](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-tpp-cas-01-02-0.md) [Analysis of Chimassorb 944 (CAS No. 71878-19-8)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-chimassorb-944.md) [Analysis of BHT (butylated hydroxytoluene) CAS No. 128-37-0](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-bht-cas-128-37-0.md) [Analysis of Irganox 1010 (CAS No. 6683-19-8), Irganox 1076 (CAS No. 2082-79-3), Irganox 3114 (CAS No. 27676-62-6)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-additives-irganox-1010-1076-3114.md) [Analysis of Tinuvin 770 (CAS No. 52829-07-9), Tinuvin 622 (CAS No. 65447-77-0), Tinuvin 327 (CAS No. 3864-99-1), Tinuvin 328 (CAS No. 25973-55-1), Tinuvin P (CAS No. 2440-22-4)](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-tinuvin.md) [Analysis of DBP (dibutyl phthalate) CAS No. 84-74-2](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polymer-additives/analysis-organic-additives-dbp.md) ## FILAB meets your TOTM (trimellitate) analysis needs CAS No. 3319-31-1 ### Our resources for the analysis of TOTM (trimellitate) CAS No. 3319-31-1 [### HPLC To separate and quantify TOTM from the other ingredients in the formula](https://filab.fr/en/our-technical-resources/laboratory-analysis-uplc.md) [### GC-MS To identify and quantify TOTM](https://filab.fr/en/our-technical-resources/laboratory-analysis-gcms.md) [### LC-MSMS To detect and quantify traces of TOTM or its degradation products](https://filab.fr/en/our-technical-resources/altis-lc-msms-analysis.md) [### FTIR For qualitative analysis on samples of pure TOTM or in the raw material](https://filab.fr/en/our-technical-resources/laboratory-analysis-ftir-spectroscopy.md) ## Why choose FILAB for the analysis of organic additives: TOTM (trimellitate) CAS No. 3319-31-1 For over ten years, the FILAB laboratory has developed extensive expertise in [chemical analysis](https://filab.fr/en/our-services/our-analysis-services/chemical-analysis-laboratory.md).

TOTM is a high-performance trimellitate plasticizer used to improve the flexibility and heat resistance of polymers, particularly PVC. It is known for its very low volatility and low tendency to migrate, making it a preferred additive in demanding environments. Why analyze TOTM in a material? The analysis allows verification of the actual plasticizer content, monitoring of its stability within the matrix, and detection of any degradation products. This information is crucial for ensuring the material's longevity and anticipating aging issues. In which sectors is TOTM most used? It is commonly used in medical (tubing, flexible devices), automotive, technical cables or applications requiring high thermal resistance or low migration. What analytical techniques can be used to quantify TOTM? The most suitable methods rely on chromatography (GC-MS, LC-MS), allowing for precise identification of the plasticizer and its derivatives even at low concentrations. Complementary approaches can be used depending on the matrix (FTIR, TGA, etc.). Why monitor TOTM degradation products? Under the influence of heat or time, TOTM can decompose and generate by-products that may affect the material's performance. Monitoring these by-products is essential to ensure the stability of the formulation, particularly in applications subject to high thermal or mechanical stresses. When should a TOTM analysis be performed? Analysis is recommended during the development of a new formulation, as part of regular quality control, after accelerated aging, or when a performance or migration problem is observed. What validates a complete TOTM analysis? It provides a comprehensive view of the quantity of additive, its stability, its interaction with other components of the formulation and compliance with sector requirements (medical, electrical, automotive, etc.).
