Description
As a certified reference material (CRM), 1,1-Difluoro-1,2,2-trichloroethane 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.
CATO supplies 1,1-Difluoro-1,2,2-trichloroethane (CAS 354-21-2), a certified reference material (molecular formula C2HCl3F2, MW 169.39 g/mol) for analytical method development and quality control.
Owing to fluorine/chlorine substitution, 1,1-Difluoro-1,2,2-trichloroethane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.39 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
