Chemical Structure

(R)-2-((tert-butoxycarbonyl)amino)-4-(2,4-difluorophenyl)butanoic acid CAS 1260618-19-6 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 (R)-2-((tert-butoxycarbonyl)amino)-4-(2,4-difluorophenyl)butanoic acid.

CATO supplies (R)-2-((tert-butoxycarbonyl)amino)-4-(2,4-difluorophenyl)butanoic acid (CAS 1260618-19-6), a certified reference material (molecular formula C15H19F2NO4, MW 315.31 g/mol) for analytical method development and quality control.

The molecular framework of (R)-2-((tert-butoxycarbonyl)amino)-4-(2,4-difluorophenyl)butanoic acid (C15H19F2NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), (R)-2-((tert-butoxycarbonyl)amino)-4-(2,4-difluorophenyl)butanoic acid 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.
