Chemical Structure

2-Bromobutane CAS 78-76-2 chemical structure

Description

As a certified reference material (CRM), 2-Bromobutane 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.

CATO supplies 2-Bromobutane (CAS 78-76-2), a certified reference material (molecular formula C4H9Br, MW 137.02 g/mol) for analytical method development and quality control.

2-Bromobutane (C4H9Br) 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.
