Chemical Structure

(R)-2-((tert-Butoxycarbonyl)amino)-2-(2,4-difluorophenyl)acetic acid CAS 1162696-80-1 chemical structure

Description

The occurrence of (R)-2-((tert-Butoxycarbonyl)amino)-2-(2,4-difluorophenyl)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (R)-2-((tert-Butoxycarbonyl)amino)-2-(2,4-difluorophenyl)acetic acid (CAS 1162696-80-1), a certified reference material (molecular formula C13H15F2NO4, MW 287.26 g/mol) for analytical method development and quality control.

The molecular framework of (R)-2-((tert-Butoxycarbonyl)amino)-2-(2,4-difluorophenyl)acetic acid (C13H15F2NO4) 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).

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), (R)-2-((tert-Butoxycarbonyl)amino)-2-(2,4-difluorophenyl)acetic 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.
