Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 211.01 g/mol gives (S)-2-Bromopentanedioic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-2-Bromopentanedioic acid (CAS 1233873-77-2), molecular formula C5H7BrO4 and molecular weight 211.01 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-2-Bromopentanedioic acid (C5H7BrO4) contains a carbohydrate-derived structure, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Bromopentanedioic 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.
