Chemical Structure

2,3-dihydroxy-3-methylbutanoic Acid CAS 1756-18-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-dihydroxy-3-methylbutanoic Acid.

CATO supplies 2,3-dihydroxy-3-methylbutanoic Acid (CAS 1756-18-9), a certified reference material (molecular formula C5H10O4, MW 134.13 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, 2,3-dihydroxy-3-methylbutanoic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.13 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.
