Chemical Structure
Description
CATO supplies (2E)-4,4-Dibromo-2-chloro-3-formyl-2-butenoic Acid (CAS 441304-67-2), a certified reference material (molecular formula C5H3Br2ClO3, MW 306.34 g/mol) for analytical method development and quality control.
The molecular framework of (2E)-4,4-Dibromo-2-chloro-3-formyl-2-butenoic Acid (C5H3Br2ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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 (2E)-4,4-Dibromo-2-chloro-3-formyl-2-butenoic 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.
