Naratriptan impurities and related standards

Naratriptan is held here as a working collection of 89 reference materials across 24 CAS numbers. 45 of the entries are impurity-type materials of the parent, 4 are salt or counter-ion variants and 5 carry a deuterium label and 18 are nitrosamine analogues. 23 entries carry a verified structure drawing, a coverage of 26%; the rest are listed without a structure rather than with an unverified one. 23 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 66 remain tier C and are kept for search coverage. The practical difficulty with a series of this size is not obtaining any one impurity but demonstrating that the set is complete. A validation package normally needs the specified impurities plus the unspecified ones above the reporting threshold, and the second group is where a catalogue either holds the material or does not. 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 Naratriptan-related reference standards do you hold?
24 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 24 of them and 24 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Naratriptan 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 Naratriptan 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 Naratriptan 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.
