Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-2-3-4-6-Penta-O-acetyl-β-D-galactopyranose (CAS 4163-60-4), molecular formula C16H22O11 and molecular weight 390.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-2-3-4-6-Penta-O-acetyl-β-D-galactopyranose (C16H22O11) is characterized by 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 1-2-3-4-6-Penta-O-acetyl-β-D-galactopyranose 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.
