Glutamine impurities and related standards

Glutamine is held here as a working collection of 47 reference materials across 13 CAS numbers. Within the range, numbered impurities go up to 79. 34 of the entries are impurity-type materials of the parent, 1 carry a deuterium label. 15 entries carry a verified structure drawing, a coverage of 32%; the rest are listed without a structure rather than with an unverified one. 13 of them sit in tier A or B, meaning the data behind the page is complete enough to be indexed and quoted directly, while 34 remain tier C and are kept for search coverage. Because these are degradation and process impurities of a single parent, the useful comparison between suppliers is not the headline count but which letters are actually covered and whether each one arrives with a structure and a stated content basis. Anyone comparing two suppliers on this parent should ask the same three questions of each: which letters are held, what the content basis is, and whether the structure on the page was verified against the name rather than copied from it.

Frequently asked

How many Glutamine-related reference standards do you hold?
22 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 22 of them and 22 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Glutamine 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 Glutamine 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 Glutamine 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.
