Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Triethyl(methyl)phosphonium dibutyl phosphate.
CATO supplies Triethyl(methyl)phosphonium dibutyl phosphate (CAS 947601-92-5), a certified reference material (molecular formula C8H18O4PC7H18P, MW 342.40 g/mol) for analytical method development and quality control.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Triethyl(methyl)phosphonium dibutyl phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
