Chlorothiazide impurities and related standards

Chlorothiazide is held here as a working collection of 8 reference materials across 1 CAS numbers. Within the range, 1 EP-designated impurities are named explicitly. 2 of the entries are impurity-type materials of the parent, 1 are nitrosamine analogues. 1 entries carry a verified structure drawing, a coverage of 12%; the rest are listed without a structure rather than with an unverified one. 1 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 7 remain tier C and are kept for search coverage. These are commodity chemistry rather than a drug impurity series, which changes what a buyer should check. The identity is usually straightforward; what varies between suppliers is the trace profile and the water content, and both of those show up in a specification rather than on a chromatogram. These are the materials most often bought on price alone, and the two places that shows up later are residual solvent and trace metal content, neither of which is visible in a chromatographic purity figure.

Frequently asked

How many Chlorothiazide-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 Chlorothiazide 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 Chlorothiazide 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 Chlorothiazide 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.
