Chemical Structure

(E)-4-Bromo-1-chloro-2-methyl-2-butene CAS 114506-04-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies (E)-4-Bromo-1-chloro-2-methyl-2-butene (CAS 114506-04-6), a certified reference material (molecular formula C5H8BrCl, MW 183.47 g/mol) for analytical method development and quality control.

Structurally, (E)-4-Bromo-1-chloro-2-methyl-2-butene (C5H8BrCl) contains chlorine/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 183.47 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
