(2S)-2-Methylbutanoyl Chloride CAS 27763-54-8

Description

Compared with other compounds in its class, the molecular weight of 120.58 g/mol gives (2S)-2-Methylbutanoyl Chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (2S)-2-Methylbutanoyl Chloride (CAS 27763-54-8), a certified reference material (molecular formula C5H9ClO, MW 120.58 g/mol) for analytical method development and quality control.

Structurally, (2S)-2-Methylbutanoyl Chloride (C5H9ClO) contains a hydroxyl group, an ether linkage, chlorine 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 120.58 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.
