Reserpine impurities and related standards

Reserpine is held here as a working collection of 28 reference materials across 10 CAS numbers. Within the range, numbered impurities go up to 16. 18 of the entries are impurity-type materials of the parent, 2 are salt or counter-ion variants and 1 carry a deuterium label. 9 entries carry a verified structure drawing, a coverage of 32%; 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 19 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. For a laboratory setting specifications, the workable sequence is to fix the impurity list from the monograph and the degradation study first, and only then to source the standards, because the list determines which materials are worth holding.

Frequently asked

How many Reserpine-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 Reserpine 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 Reserpine 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 Reserpine 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.
