Compared with other compounds in its class, the molecular weight of 132.16 g/mol gives 4-methoxy-2-methylbutanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-methoxy-2-methylbutanoic acid (CAS 35841-41-9), molecular formula C6H12O3 and molecular weight 132.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4-methoxy-2-methylbutanoic acid 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
