Use L-Selenomethionine for stereochemical identity checks, selenium-compound documentation, raw-material comparison, and research planning tied to CAS 3211-76-5.
L-Selenomethionine is identified by CAS 3211-76-5, molecular formula C5H11NO2Se, and molecular weight 196.11. The L/2S stereochemical identity is used for clarity.
Key identity terms include L-Selenomethionine, Seleno-L-methionine, SeMet, and (2S)-2-amino-4-methylselanylbutanoic acid. Malformed, mixed-isomer, and grade-style fragments are not used as customer-facing synonyms.
L-Selenomethionine may be used in selenium-compound identity evaluation, raw-material comparison, and supplier-document workflows where a CAS-verified amino-acid identity is required.
