Ceramide impurities and related standards

Ceramide is held here as a working collection of 13 reference materials across 10 CAS numbers. 10 entries carry a verified structure drawing, a coverage of 77%. 10 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. The labelled members of this group are used as internal standards, which puts the isotopic distribution at the centre of the specification rather than at its edge: the label position and the enrichment have to be stated, and a co-eluting unlabelled fraction changes the result even when the chemical purity looks acceptable. 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 Ceramide-related reference standards do you hold?
11 standards are listed on this page as of the latest catalogue build. CAS numbers are published for 11 of them and 11 entries carry a structure drawing. The catalogue is extended as new lots are released.
Can you supply a Ceramide 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 Ceramide 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 Ceramide 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.
