Secnidazole impurities and related standards

Secnidazole is held here as a working collection of 12 reference materials across 3 CAS numbers. 3 of the entries are impurity-type materials of the parent, 1 are salt or counter-ion variants and 2 carry a deuterium label. 2 entries carry a verified structure drawing, a coverage of 17%; the rest are listed without a structure rather than with an unverified one. 2 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 10 remain tier C and are kept for search coverage. Relative response factors are what decide whether a percentage on a chromatogram means anything. Impurities that lack a chromophore, or whose ultraviolet maximum sits away from the detection wavelength used for the parent, under-respond by a factor that has to be established with a solution of the standard itself rather than assumed. Where the impurity is a chiral species, the enantiomeric ratio belongs on the specification alongside the chemical purity, because an achiral method reports the two together as one peak.

Frequently asked

How many Secnidazole-related reference standards do you hold?
2 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 2 of them and 2 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Secnidazole 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 Secnidazole 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 Secnidazole 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.
