Description
CATO supplies 30DEK38OFS 1832-54-8 Isopropyl methylphosphonic acid Phosphonic acid, methyl-, mono(1-methylethyl) ester Phosphonic acid, methyl, monoisopropyl ester IMPA Phosphonic acid, methyl isopropyl ester Isopropyl methylphosphonate Monoisopropyl methylphosphonate O-Isoproyl hydrogen methylphosphonate UNII-30DEK38OFS IMP (CAS 1832-54-8), a certified reference material (molecular formula C4H11O3P, MW 138.10 g/mol) for analytical method development and quality control.
30DEK38OFS 1832-54-8 Isopropyl methylphosphonic acid Phosphonic acid, methyl-, mono(1-methylethyl) ester Phosphonic acid, methyl, monoisopropyl ester IMPA Phosphonic acid, methyl isopropyl ester Isopropyl methylphosphonate Monoisopropyl methylphosphonate O-Isoproyl hydrogen methylphosphonate UNII-30DEK38OFS IMP (C4H11O3P) contains a phosphonate group, 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.
