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 2,2'-oxybis(2,2-difluoroacetic acid) (CAS 6535-10-0), a certified reference material (molecular formula C4H2F4O5, MW 206.05 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, fluorine substitution, 2,2'-oxybis(2,2-difluoroacetic acid) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.05 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), 2,2'-oxybis(2,2-difluoroacetic acid) 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.
