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.
CATO supplies Methyl Propylene Phosphate (CAS 33554-05-1), a certified reference material (molecular formula C4H9O4P, MW 152.09 g/mol) for analytical method development and quality control.
Methyl Propylene Phosphate (C4H9O4P) contains a carbohydrate-derived structure, a phosphate ester group. 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.
