Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-amino-4,4-difluorobutanoate.
CATO supplies Ethyl 3-amino-4,4-difluorobutanoate (CAS 81982-55-0), a certified reference material (molecular formula C6H11F2NO2, MW 167.15 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H11F2NO2, Ethyl 3-amino-4,4-difluorobutanoate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 167.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Ethyl 3-amino-4,4-difluorobutanoate 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.
