Chemical Structure
Description
The occurrence of (S)-2-Bromosuccinic Acid is closely related to a carbohydrate-derived structure, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-2-Bromosuccinic Acid (CAS 20859-23-8), molecular formula C4H5BrO4 and molecular weight 196.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-2-Bromosuccinic Acid (C4H5BrO4) 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.
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.
CATO manufactures (S)-2-Bromosuccinic Acid 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.
