L-(+)-Ergothioneine CAS 497-30-3 chemical structure

Description

L-(+)-Ergothioneine (CAS 497-30-3) is a high-purity analytical reference standard with the molecular formula C9H15N3O2S and a molecular weight of 229.30 g/mol.

L-(+)-Ergothioneine (C9H15N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures L-(+)-Ergothioneine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
