# Analysis and determination of DnBP

## You wish to carry out the analysis and determination of DnBP

First of all, DnBP (Di-n-butyl) is a herbicide of the dinitrophenol family of [phthalates](https://filab.fr/en/our-services/our-analysis-services/chemical-analysis-laboratory/analysis-and-determination-of-phthalates-in-the-laboratory.md). It is an orange crystalline solid. DnBP is banned as a herbicide in the European Union and the United States due to its toxicity.

However, it is used as a **polymerisation inhibitor**. It is used to prevent thermally induced polymerisation of styrene and other unsaturated monomers during their purification by distillation.

Therefore, the support of a laboratory with state-of-the-art analytical equipment for [phthalate analysis](https://filab.fr/en/our-services/our-analysis-services/chemical-analysis-laboratory/analysis-and-determination-of-phthalates-in-the-laboratory.md) is essential for the analysis and determination of DnBP.

## FILAB meets your needs for DnBP analysis and determination

In order to support manufacturers in the development and quality control of their products, by following the regulatory evolutions, the FILAB laboratory makes available a state-of-the-art analytical facility of 5200m², allowing to carry out the analysis and the dosage of DnBP.
