Acute toxicity - oral GHS chapter 3.1 Category 3 H301 GHS06

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 Octhilinone (ISO)

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 Octhilinone (ISO) 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

Octhilinone (ISO) precautionary statements

CLP Annex VI assigns 20 precautionary statements to Octhilinone (ISO). 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

Octhilinone (ISO) 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.

Octhilinone (ISO) storage and handling

Octhilinone (ISO) storage conditions

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Storage class (TRGS 510): Non-combustible, acute toxic Cat.3 / toxic hazardous materials or hazardous materials causing chronic effects.

Octhilinone (ISO) incompatible materials

Incompatible materials: Strong oxidizing agents.

Source: Hazardous Substances Data Bank (HSDB)

Octhilinone (ISO) reactivity

2-OCTYL-3-ISOTHIAZOLONE reacts as an isothiocyanate. Isothiocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat.

What is the CAS number of Octhilinone (ISO)?

The CAS number of Octhilinone (ISO) is 26530-20-1. Its EC number is 247-761-7.

What does a Octhilinone (ISO) label have to show?

Under CLP Annex VI the label for Octhilinone (ISO) carries the pictograms Skull and crossbones, Corrosion and Environment and the signal word is Danger.

Is Octhilinone (ISO) flammable?

CLP Annex VI assigns Octhilinone (ISO) 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 93.33 °C (200 °F), above this value (CAMEO).

Is Octhilinone (ISO) a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Octhilinone (ISO). 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 boiling point of Octhilinone (ISO)?

The boiling point reported for Octhilinone (ISO) is 120 °C (248 °F), at 0.01 mmHg (reduced pressure) (HSDB).

What is the melting point of Octhilinone (ISO)?
