Description
As a certified reference material (CRM), ethyl 2-chloro-3,3,3-trifluoro-2-(propionylamino)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.
CATO supplies ethyl 2-chloro-3,3,3-trifluoro-2-(propionylamino)propanoate (CAS 328270-31-1), a certified reference material (molecular formula C8H11ClF3NO3, MW 261.63 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/chlorine substitution, ethyl 2-chloro-3,3,3-trifluoro-2-(propionylamino)propanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.63 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.
