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 methyl 3-amino-2,2-difluoro-propanoate (CAS 688736-21-2), a certified reference material (molecular formula C4H7F2NO2, MW 139.10 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, methyl 3-amino-2,2-difluoro-propanoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.10 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), methyl 3-amino-2,2-difluoro-propanoate 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.
