Description
Compared with other compounds in its class, the molecular weight of 254.08 g/mol gives (R)-2-Amino-3-(3-chloro-4-fluorophenyl)propanoic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-2-Amino-3-(3-chloro-4-fluorophenyl)propanoic acid hydrochloride (CAS 457654-79-4), molecular formula C9H9ClFNO2HCl and molecular weight 254.08 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-2-Amino-3-(3-chloro-4-fluorophenyl)propanoic acid hydrochloride (C9H9ClFNO2HCl) 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, 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.
