Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-3-4-Tri-O-acetyl-D-arabinopyranosyl bromide - Stabilised with 2% CaCO3 (CAS 113889-50-2), a certified reference material (molecular formula C5H9BrO4C2H4O2, MW 273.08 g/mol) for analytical method development and quality control.
The molecular framework of 2-3-4-Tri-O-acetyl-D-arabinopyranosyl bromide - Stabilised with 2% CaCO3 (C5H9BrO4C2H4O2) is characterized by a carbohydrate-derived structure, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 2-3-4-Tri-O-acetyl-D-arabinopyranosyl bromide - Stabilised with 2% CaCO3 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.
