(4E)-5-Bromopent-4-enoic acid CAS 88663-50-7 chemical structure

Description

CATO manufactures (4E)-5-Bromopent-4-enoic 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.

(4E)-5-Bromopent-4-enoic acid (CAS 88663-50-7), molecular formula C5H7BrO2 and molecular weight 179.01 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, (4E)-5-Bromopent-4-enoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 179.01 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.
