Lambda-Cyhalothrin hazard classification

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

Lambda-Cyhalothrin hazard class and category

GHS hazard classes Lambda-Cyhalothrin falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 3 H301 GHS06
Acute toxicity - dermal GHS chapter 3.1 Category 4 H312 GHS07
Acute toxicity - inhalation GHS chapter 3.1 Category 1 or 2 H330 GHS06
Hazardous to the aquatic environment - acute GHS chapter 4.1 Category 1 H400 GHS09
Hazardous to the aquatic environment - chronic GHS chapter 4.1 Category 1 H410 GHS09

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 Lambda-Cyhalothrin

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 Lambda-Cyhalothrin 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

Lambda-Cyhalothrin precautionary statements

CLP Annex VI assigns 14 precautionary statements to Lambda-Cyhalothrin. 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.

05 · Names in the regulation

Lambda-Cyhalothrin 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 · Questions

Lambda-Cyhalothrin — frequently asked questions

What is the CAS number of Lambda-Cyhalothrin?

The CAS number of Lambda-Cyhalothrin is 91465-08-6. Its EC number is 415-130-7.

What is the chemical formula of Lambda-Cyhalothrin?

The molecular formula of Lambda-Cyhalothrin is C23H19ClF3NO3 and its molecular weight is 449.8 g/mol.

What does a Lambda-Cyhalothrin label have to show?

Under CLP Annex VI the label for Lambda-Cyhalothrin carries the pictograms Skull and crossbones and Environment and the signal word is Danger.

Is Lambda-Cyhalothrin flammable?

CLP Annex VI assigns Lambda-Cyhalothrin 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.

Is Lambda-Cyhalothrin a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Lambda-Cyhalothrin. 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.

What is the melting point of Lambda-Cyhalothrin?

The melting point reported for Lambda-Cyhalothrin is 49.2 °C (120.6 °F) (ICSC).
