Questions for this material

Does the listed 99% establish every aspect of an L-serine grade?

The listing names L-Serine, CAS 56-45-1 and an HPLC method label. Request the actual analyte, method and reporting basis, including any stereochemical criterion your specification requires. This source does not report a separate stereochemical result.

How should I distinguish this from the glycine record?

Specify L-Serine by its exact identity rather than by the shared white-powder appearance or 99% statement. The separately listed Glycine Powder has source CAS 56-40-6; sharing an amino-acid category does not make the materials substitutes.
