Safety Data Sheet
Getting an SDS for Sodium 2-biphenylate
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 Sodium 2-biphenylate 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
Sodium 2-biphenylate precautionary statements
CLP Annex VI assigns 16 precautionary statements to Sodium 2-biphenylate. 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
Sodium 2-biphenylate 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.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

Sodium 2-biphenylate carcinogenicity classification
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.
08 · Physical and chemical properties
Sodium 2-biphenylate properties
Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.
Sodium 2-biphenylate solubility

|---|---|---|---|
| Solubility | greater than or equal to 100 mg/mL at 68 °F (NTP, 1992) | at 20 °C | CAMEO |

09 · Handling and storage
Sodium 2-biphenylate storage and handling
Sodium 2-biphenylate reactivity
Salts, basic, such as SODIUM O-PHENYLPHENOXIDE are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

10 · Questions
Sodium 2-biphenylate — frequently asked questions
What is the CAS number of Sodium 2-biphenylate?
The CAS number of Sodium 2-biphenylate is 132-27-4. Its EC number is 205-055-6.
What does a Sodium 2-biphenylate label have to show?
Under CLP Annex VI the label for Sodium 2-biphenylate carries the pictograms Corrosion, Exclamation mark and Environment and the signal word is Warning.
Is Sodium 2-biphenylate flammable?
CLP Annex VI assigns Sodium 2-biphenylate 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 Sodium 2-biphenylate a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Sodium 2-biphenylate. 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. IARC places it in Group 2B: possibly carcinogenic to humans.
