Meprobamate impurities and related standards

Meprobamate is held here as a working collection of 9 reference materials across 7 CAS numbers. 6 entries carry a verified structure drawing, a coverage of 67%. 6 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 3 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. 7 of the 9 entries carry a registered CAS number; the remaining 2 are described by structure and name alone.

Frequently asked

How many Meprobamate-related reference standards do you hold?
6 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 6 of them and 6 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Meprobamate 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 Meprobamate 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 Meprobamate 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.
