Chemical Structure

2-Bromopentanedioic acid CAS 51528-22-4 chemical structure

Description

CATO manufactures 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.

2-Bromopentanedioic acid (CAS 51528-22-4), molecular formula C5H7BrO4 and molecular weight 211.01 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, bromine substitution, 2-Bromopentanedioic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
