Chemical Structure

Methyl 4-hydroxy-3-methylbutanoate CAS 65080-82-2 chemical structure

Description

Methyl 4-hydroxy-3-methylbutanoate (CAS 65080-82-2), molecular formula C6H12O3 and molecular weight 132.16 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H12O3, Methyl 4-hydroxy-3-methylbutanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 132.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
