Pimozide impurities and related standards

Pimozide is held here as a working collection of 47 reference materials across 16 CAS numbers. Within the range, the lettered series reaches E; numbered impurities go up to 5. and 2 EP-designated impurities are named explicitly 31 of the entries are impurity-type materials of the parent, 12 carry a deuterium label and 1 are nitrosamine analogues. 14 entries carry a verified structure drawing, a coverage of 30%; the rest are listed without a structure rather than with an unverified one. 14 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 33 remain tier C and are kept for search coverage. Isotopically labelled standards are judged on the distribution rather than on a single purity number, because a material that is 99 per cent pure chemically can still carry a substantial unlabelled fraction, and that fraction is what biases a quantitative assay. A certificate that names the synthetic route the standard was qualified against is more useful than one that only reports purity, since the same impurity can arise from two routes and only one of them will be present in a given product.

Frequently asked

How many Pimozide-related reference standards do you hold?
16 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 16 of them and 16 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Pimozide 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 Pimozide 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 Pimozide 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.
