Chemical Structure
Description
CATO supplies Methyl Orthoformate (CAS 149-73-5), a certified reference material (molecular formula C4H10O3, MW 106.12 g/mol) for analytical method development and quality control.
Methyl Orthoformate (C4H10O3) 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.
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.
