Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Dimethyl(3-(methylsulfonyl)-4-(prop-2-yn-1-ylamino)phenyl)phosphine oxide (CAS 2903924-26-3) is a high-purity analytical reference standard with the molecular formula C12H16NO3PS and a molecular weight of 285.30 g/mol.
Dimethyl(3-(methylsulfonyl)-4-(prop-2-yn-1-ylamino)phenyl)phosphine oxide (C12H16NO3PS) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
