Sulfacetamide impurities and related standards

Sulfacetamide is held here as a working collection of 10 reference materials across 5 CAS numbers. Within the range, the lettered series reaches E. and 2 EP-designated impurities are named explicitly 4 of the entries are impurity-type materials of the parent, 2 are salt or counter-ion variants and 2 carry a deuterium label. 5 entries carry a verified structure drawing, a coverage of 50%; the rest are listed without a structure rather than with an unverified one. 5 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 5 remain tier C and are kept for search coverage. Storage behaviour differs across a series like this even when the parent is stable. The N-oxides and the hydroxylated analogues are the ones that drift upward on standing, and a certificate that states storage conditions without saying which degradant was monitored leaves the user unable to tell whether a rise on stability is the material or the handling. Where a letter exists in a monograph but not in a supplier catalogue, that gap is what stops a validation study, and it is worth asking for the letter rather than for a percentage.

Frequently asked

How many Sulfacetamide-related reference standards do you hold?
6 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 6 of them and 6 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Sulfacetamide impurity that is not listed here?
Yes. Non-compendial impurities can be quoted from a structure — a CAS number is not required. Send the structure, a SMILES string or the parent drug substance with your enquiry and we will come back with availability.
What documentation is supplied with Sulfacetamide impurities?
Every lot ships with its own certificate of analysis. The certificate records the catalogue number, the batch number, the tests performed, the specification applied and the result obtained for that lot. A safety data sheet is supplied with the shipment.
Do you publish prices or a lead time for Sulfacetamide impurities?
No price list is published: quotations are prepared per enquiry, because availability and packing depend on the lot and the quantity you need. Send the catalogue number and the quantity and a technical contact will answer with availability and a quotation.
