03 · GHS classification

Diethyl(ethyldimethylsilanolat… hazard classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

Diethyl(ethyldimethylsilanolat… hazard class and category

GHS hazard classes Diethyl(ethyldimethylsilan… falls into
Hazard class Category From code Pictogram
Pyrophoric liquids or Pyrophoric solids Category 1 H250 GHS02
In contact with water emits flammable gases GHS chapter 2.12 Category 1 H260 GHS02
Skin corrosion/irritation GHS chapter 3.2 Category 1A or 1B or 1C H314 GHS05

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for Diethyl(ethyldimethylsilan…

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 Diethyl(ethyldimethyls… 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

Diethyl(ethyldimethylsilanolat… precautionary statements

Response

05 · Names in the regulation

Diethyl(ethyldimethylsilanolat… 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.
