Chemical Structure

2-(Bromomethyl)-1-butene CAS 59032-45-0 chemical structure

Description

CATO supplies 2-(Bromomethyl)-1-butene (CAS 59032-45-0), a certified reference material (molecular formula C5H9Br, MW 149.03 g/mol) for analytical method development and quality control.

Structurally, 2-(Bromomethyl)-1-butene (C5H9Br) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 149.03 g/mol, it falls into the low-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
