Safety Data Sheet
Getting an SDS for Diphenylguanidine
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 Diphenylguanidine 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
Diphenylguanidine precautionary statements
CLP Annex VI assigns 16 precautionary statements to Diphenylguanidine. 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
Diphenylguanidine 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.

Diphenylguanidine reactivity
1,3-DIPHENYLGUANIDINE behaves as an amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. This chemical is incompatible with strong oxidizers. (NTP, 1992)

What does a Diphenylguanidine label have to show?
Under CLP Annex VI the label for Diphenylguanidine carries the pictograms Health hazard, Exclamation mark and Environment and the signal word is Warning.
Is Diphenylguanidine flammable?
CLP Annex VI assigns Diphenylguanidine 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 197.78 °C (388 °F) (CAMEO).
Is Diphenylguanidine a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Diphenylguanidine. 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 Diphenylguanidine?
The boiling point reported for Diphenylguanidine is 170 °C (338 °F), above this value (CAMEO).
What is the melting point of Diphenylguanidine?
The melting point reported for Diphenylguanidine is 150 °C (302 °F) (HSDB).
