Description

(3R,4S)-3-amino-4-methyl-hexanoic acid;hydrochloride (3R,4S)-3-amino-4-methylhexanoic acid;hydrochloride (3R,4S)-3-azanyl-4-methyl-hexanoic acid;hydrochloride 219310-10-8 L-beta-homoisoleucine-HCl (CAS 219310-10-8) is a high-purity analytical reference standard with the molecular formula C7H15NO2HCl and a molecular weight of 181.66 g/mol.

Structurally, (3R,4S)-3-amino-4-methyl-hexanoic acid;hydrochloride (3R,4S)-3-amino-4-methylhexanoic acid;hydrochloride (3R,4S)-3-azanyl-4-methyl-hexanoic acid;hydrochloride 219310-10-8 L-beta-homoisoleucine-HCl (C7H15NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 181.66 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
