Chemical Structure

(S)-3-Hydroxyisobutyric Acid CAS 2068-83-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 104.10 g/mol gives (S)-3-Hydroxyisobutyric Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-3-Hydroxyisobutyric Acid (CAS 2068-83-9) is a high-purity analytical reference standard with the molecular formula C4H8O3 and a molecular weight of 104.10 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (S)-3-Hydroxyisobutyric Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.10 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.
