(S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-difluorobenzyl)propanoic acid CAS 1260594-34-0 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)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-difluorobenzyl)propanoic acid.

(S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-difluorobenzyl)propanoic acid (CAS 1260594-34-0) is a high-purity analytical reference standard with the molecular formula C25H21F2NO4 and a molecular weight of 437.44 g/mol.

The molecular framework of (S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-difluorobenzyl)propanoic acid (C25H21F2NO4) is characterized by a flavonoid core, 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), (S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-difluorobenzyl)propanoic 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.
