Clavulanate impurities and related standards

Clavulanate is held here as a working collection of 12 reference materials across 6 CAS numbers. Within the range, the lettered series reaches K. and 3 EP-designated impurities are named explicitly 3 of the entries are impurity-type materials of the parent, 1 carry a deuterium label. 6 entries carry a verified structure drawing, a coverage of 50%; the rest are listed without a structure rather than with an unverified one. 6 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 6 remain tier C and are kept for search coverage. Each of these materials is normally supplied with its own chromatographic purity and its own content basis, and the two numbers are not interchangeable. A standard quoted at 98 per cent by area can be materially lower by mass once residual solvent and water are counted, which changes the weight a laboratory has to weigh. Anyone comparing two suppliers on this parent should ask the same three questions of each: which letters are held, what the content basis is, and whether the structure on the page was verified against the name rather than copied from it.

Frequently asked

How many Clavulanate-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 Clavulanate 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 Clavulanate 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 Clavulanate 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.
