Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Methylumbelliferyl beta-D-Galactopyranoside-6-sulfate sodium salt (CAS 206443-06-3), molecular formula C16H23O11SNa and molecular weight 446.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Methylumbelliferyl beta-D-Galactopyranoside-6-sulfate sodium salt (C16H23O11SNa) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 4-Methylumbelliferyl beta-D-Galactopyranoside-6-sulfate sodium salt 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.
