Safety Data Sheet

Getting an SDS for Trixylenyl phosphate

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Trixylenyl phosphate issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements

Trixylenyl phosphate precautionary statements

CLP Annex VI assigns 4 precautionary statements to Trixylenyl phosphate. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

Response

What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation

Trixylenyl phosphate name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

09 · Handling and storage

Trixylenyl phosphate storage and handling

Trixylenyl phosphate incompatible materials

This product is incompatible with strong oxidizers, strong acids and strong alkalis. It hydrolyzes slowly at ambient temperatures in acidic or alkaline aqueous solutions.

Source: Hazardous Substances Data Bank (HSDB)

Trixylenyl phosphate reactivity

Organophosphates, such as TRIXYLENYL PHOSPHATE, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

What is the CAS number of Trixylenyl phosphate?

The CAS number of Trixylenyl phosphate is 25155-23-1. Its EC number is 246-677-8.

What is the chemical formula of Trixylenyl phosphate?

The molecular formula of Trixylenyl phosphate is C24H27O4P and its molecular weight is 410.4 g/mol.

What does a Trixylenyl phosphate label have to show?

Under CLP Annex VI the label for Trixylenyl phosphate carries the pictogram Health hazard and the signal word is Danger.

Is Trixylenyl phosphate flammable?

CLP Annex VI assigns Trixylenyl phosphate no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it. The flash point reported for it is 232.22 °C (450 °F) (CAMEO).

Is Trixylenyl phosphate a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Trixylenyl phosphate. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.
