CATO supplies 3279-26-3 Dichloro Methyl Phosphite Dichloromethoxyphosphine Methoxydichlorophosphine Methoxyphosphonous Dichloride Methyl dichlorophosphite Methyl phosphorodichloridite O-Methyl Phosphorodichloridite (CAS 3279-26-3), a certified reference material (molecular formula CH3Cl2OP, MW 132.91 g/mol) for analytical method development and quality control.
3279-26-3 Dichloro Methyl Phosphite Dichloromethoxyphosphine Methoxydichlorophosphine Methoxyphosphonous Dichloride Methyl dichlorophosphite Methyl phosphorodichloridite O-Methyl Phosphorodichloridite (CH3Cl2OP) contains organophosphorus functionality, a hydroxyl group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
