(1,1'-Biphenyl)-2-ol hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Skin corrosion/irritation GHS chapter 3.2 | Category 1A or 1B or 1C | H314 | GHS05 |
| Serious eye damage/eye irritation GHS chapter 3.3 | Category 1 | H318 | 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 (1,1'-Biphenyl)-2-ol
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 (1,1'-Biphenyl)-2-ol 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
(1,1'-Biphenyl)-2-ol precautionary statements
CLP Annex VI assigns 16 precautionary statements to (1,1'-Biphenyl)-2-ol. 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.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
(1,1'-Biphenyl)-2-ol 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.

(1,1'-Biphenyl)-2-ol carcinogenicity classification
Under the conditions of these 2-year dermal application studies, there was no evidence of carcinogenicity in male or female Swiss CD-1 mice administered o-phenylphenol alone or as a promoter following initiation with DMBA. o-Phenylphenol, however, caused nonneoplastic lesions, which included ulceration, inflammation, and hyperkeratosis, at the site of application.

Cancer Classification: Not Likely to be Carcinogenic to Humans
Source: Hazardous Substances Data Bank (HSDB)
Evaluation: There is inadequate evidence in humans for the carcinogenicity of ortho-phenylphenol and sodium ortho-phenylphenate. Overall evaluation: ortho-Phenylphenol is not classifiable as to its carcinogenicity to humans (Group 3). Sodium ortho-phenylphenate is possibly carcinogenic to humans (Group 2B).
Source: Hazardous Substances Data Bank (HSDB)
An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

(1,1'-Biphenyl)-2-ol storage conditions
Store in tightly closed containers in a cool, well-ventilated area away from water. Sources of ignition, such as smoking and open flames, are prohibited where o-phenylphenol is used, handled, or stored in a manner that could create a potential fire or explosion hazard.

(1,1'-Biphenyl)-2-ol reactivity
2-PHENYLPHENOL react as a weak organic acid. Exothermically neutralizes bases. May react with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides to generate flammable gas (H2) and the heat of the reaction may ignite the gas. Is sulfonated very readily (for example, by concentrated sulfuric acid at room temperature) in exothermic reactions. May be nitrated very rapidly. Nitrated phenols often explode when heated and also form metal salts that tend toward detonation by rather mild shock. Can react with oxidizing agents (NTP, 1992).
