Safety Data Sheet
Getting an SDS for 4,4'-carbonimidoylbis[N,N…
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 4,4'-carbonimidoylbis[… 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
4,4'-carbonimidoylbis[N,N-dime… precautionary statements
CLP Annex VI assigns 15 precautionary statements to 4,4'-carbonimidoylbis[N,N…. 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
4,4'-carbonimidoylbis[N,N-dime… 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.

4,4'-carbonimidoylbis[N,N-dime… carcinogenicity classification
The Human Health Assessment Group in EPA's Office of Health and Environmental Assessment has evaluated auramine for carcinogenicity. According to their analysis, the weight-of-evidence for auramine is group B2, which is based on inadequate evidence in humans and sufficient evidence in animals. As a group B2 chemical, auramine is considered probably carcinogenic to humans.
Source: Hazardous Substances Data Bank (HSDB)
Auramine, technical grade - Inadequate evidence of carcinogenicity in humans. Sufficient evidence of carcinogenicity in animals. OVERALL EVALUATION: Group 2B: The agent is possibly carcinogenic to humans. Auramine, manufacture of - Sufficient evidence of carcinogenicity in humans. No data on the carcinogenicity in animals. OVERALL EVALUATION: Group 1: The process is carcinogenic to humans.

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.
