3-Bromo-1,2-propanediol CAS 4704-77-2 chemical structure

Description

CATO manufactures 3-Bromo-1,2-propanediol 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.

3-Bromo-1,2-propanediol (CAS 4704-77-2), molecular formula C3H7BrO2 and molecular weight 154.99 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Bromo-1,2-propanediol (C3H7BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.

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.
