(S)-2-((tert-Butoxycarbonyl)amino)-3-(3-chloro-4-fluorophenyl)propanoic acid CAS 1629658-18-9 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 (S)-2-((tert-Butoxycarbonyl)amino)-3-(3-chloro-4-fluorophenyl)propanoic acid.

(S)-2-((tert-Butoxycarbonyl)amino)-3-(3-chloro-4-fluorophenyl)propanoic acid (CAS 1629658-18-9) is a high-purity analytical reference standard with the molecular formula C14H17ClFNO4 and a molecular weight of 317.74 g/mol.

(S)-2-((tert-Butoxycarbonyl)amino)-3-(3-chloro-4-fluorophenyl)propanoic acid (C14H17ClFNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (S)-2-((tert-Butoxycarbonyl)amino)-3-(3-chloro-4-fluorophenyl)propanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
