Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Methoxy-3-(oxan-4-yl)propan-2-one (CAS 1248138-49-9), molecular formula C9H16O3 and molecular weight 172.22 g/mol, is a CATO reference standard with documented purity and traceability.
1-Methoxy-3-(oxan-4-yl)propan-2-one (C9H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
