1,2,3,4-tetrahydro-1-naphthyl… hazard class and category

GHS hazard classes 1,2,3,4-tetrahydro-1-napht… falls into
Hazard class Category From code Pictogram
Organic peroxides or Self-reactive substances and mixtures Category Type C and D or Type E and F H242 GHS02
Acute toxicity - oral GHS chapter 3.1 Category 4 H302 GHS07

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 1,2,3,4-tetrahydro-1-napht…

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 1,2,3,4-tetrahydro-1-n… 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

1,2,3,4-tetrahydro-1-naphthyl… precautionary statements

CLP Annex VI assigns 11 precautionary statements to 1,2,3,4-tetrahydro-1-napht…. 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

1,2,3,4-tetrahydro-1-naphthyl… 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.

07 · Handling and storage

1,2,3,4-tetrahydro-1-naphthyl… storage and handling

1,2,3,4-tetrahydro-1-naphthyl… reactivity

Most alkyl monohydroperoxides are liquid. The explosivity of the lower members (e.g., methyl hydroperoxide, or possibly due to traces of the dialkyl peroxides) decrease with increasing chain length and branching [Bretherick 2nd ed. 1979 p. 10]. Tetralin hydroperoxide explodes on superheating the liquid [Hock et al. Ber. 1933. pp. 66, 61]. Its interaction with strong reducing agents, like lithium tetrahydroaluminate, is vigorously exothermic.
