4-Chloro-3-methyl-3-hydroxy-1-butene CAS 7437-62-9

Description

The occurrence of 4-Chloro-3-methyl-3-hydroxy-1-butene is closely related to a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Chloro-3-methyl-3-hydroxy-1-butene (CAS 7437-62-9), a certified reference material (molecular formula C5H9ClO, MW 120.58 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-3-methyl-3-hydroxy-1-butene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
