Description
CATO manufactures 1,2,3,4,6-Penta-O-benzoyl-b-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.
CATO supplies 1,2,3,4,6-Penta-O-benzoyl-b-D-galactopyranose (CAS 41545-56-6), a certified reference material (molecular formula C41H32O11, MW 700.69 g/mol) for analytical method development and quality control.
The molecular framework of 1,2,3,4,6-Penta-O-benzoyl-b-D-galactopyranose (C41H32O11) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
