Vinblastine impurities and related standards

Vinblastine is held here as a working collection of 45 reference materials across 9 CAS numbers. Within the range, the lettered series reaches H. and 2 EP-designated impurities are named explicitly 26 of the entries are impurity-type materials of the parent, 10 are salt or counter-ion variants and 9 carry a deuterium label. 9 entries carry a verified structure drawing, a coverage of 20%; the rest are listed without a structure rather than with an unverified one. 9 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 36 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. 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 Vinblastine-related reference standards do you hold?
10 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 10 of them and 10 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Vinblastine 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 Vinblastine 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 Vinblastine 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.
