Chemical Structure

Methyl (R)-2-hydroxy-3-methylbutanoate CAS 90244-32-9 chemical structure

Description

CATO supplies Methyl (R)-2-hydroxy-3-methylbutanoate (CAS 90244-32-9), a certified reference material (molecular formula C6H12O3, MW 132.16 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl (R)-2-hydroxy-3-methylbutanoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
