Metabolites are used to confirm structure assignments in metabolism studies and as calibrants in bioanalytical methods. They are not pharmacopoeially lettered impurities, so the acceptance criterion comes from your own study rather than from a monograph.
Storage. Store at 2-8 °C. Allow the container to reach room temperature before opening so that moisture does not condense onto the material. Record the date of first opening on the label.
Pack sizes. Quoted on request. Non-standard quantities are quoted on request, normally within two working days.
Documentation. Each lot is released with a certificate of analysis that states the assay method, the water content and the form as supplied. The safety data sheet is available with the same lot number. Quote catalogue number C4X-26221 when requesting either document.
Documentation
Documents are issued per lot. The COA you receive describes the lot that ships, not a representative sample.
Regulatory reference
Metabolite reference standard used for metabolite identification and bioanalytical method support. Not a pharmacopoeially lettered impurity.
References are provided to help you map a standard to a pharmacopoeial method. Confirm the acceptance criteria against your own method before use.
