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 3-Chloro-3,3-difluoroprop-1-ene (CAS 421-03-4), a certified reference material (molecular formula C3H3ClF2, MW 112.51 g/mol) for analytical method development and quality control.
Owing to fluorine/chlorine substitution, 3-Chloro-3,3-difluoroprop-1-ene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.51 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), 3-Chloro-3,3-difluoroprop-1-ene 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.
