Chemical Structure
Description
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.
1,3-Propanediol,2-(1-ethylpropyl)- (CAS 25462-28-6), molecular formula C8H18O2 and molecular weight 146.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,3-Propanediol,2-(1-ethylpropyl)- is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.23 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.
