Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl (r)-3-amino-3-(2,4-difluorophenyl)propanoate hydrochloride.
CATO supplies Ethyl (r)-3-amino-3-(2,4-difluorophenyl)propanoate hydrochloride (CAS 2126142-97-8), a certified reference material (molecular formula C11H13F2NO2HCl, MW 265.68 g/mol) for analytical method development and quality control.
Ethyl (r)-3-amino-3-(2,4-difluorophenyl)propanoate hydrochloride (C11H13F2NO2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
