Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Dimethyl 1-(Butyryloxy)-2,2,2-trichloroethylphosphonate (CAS 126-22-7), a certified reference material (molecular formula C8H14Cl3O5P, MW 327.53 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, chlorine substitution, Dimethyl 1-(Butyryloxy)-2,2,2-trichloroethylphosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Dimethyl 1-(Butyryloxy)-2,2,2-trichloroethylphosphonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
