(Z)-1-Bromo-1,3-Butadiene CAS 56318-77-5 chemical structure

Description

CATO manufactures (Z)-1-Bromo-1,3-Butadiene 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.

CATO supplies (Z)-1-Bromo-1,3-Butadiene (CAS 56318-77-5), a certified reference material (molecular formula C4H5Br, MW 132.99 g/mol) for analytical method development and quality control.

The molecular framework of (Z)-1-Bromo-1,3-Butadiene (C4H5Br) is characterized by 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.
