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-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(4-chlorophenyl)acetic acid.

(S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(4-chlorophenyl)acetic acid (CAS 1260590-28-0) is a high-purity analytical reference standard with the molecular formula C23H18ClNO4 and a molecular weight of 407.85 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(4-chlorophenyl)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-(4-chlorophenyl)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.
