Chemical Structure

1-Bromo-2-Buten CAS 29576-14-5 chemical structure

Description

CATO supplies 1-Bromo-2-Buten (CAS 29576-14-5), a certified reference material (molecular formula C4H7Br, MW 135.00 g/mol) for analytical method development and quality control.

1-Bromo-2-Buten (C4H7Br) contains bromine substitution. Halogen substitution raises its density and boiling point; 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.

As a certified reference material (CRM), 1-Bromo-2-Buten meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
