Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Methyl-1,3-butanediol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
CATO supplies 3-Methyl-1,3-butanediol (CAS 2568-33-4), a certified reference material (molecular formula C5H12O2, MW 104.15 g/mol) for analytical method development and quality control.
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.
