(R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((amino((2,4,6-trimethylphenyl)sulfonamido)methylene)amino)pentanoic acid CAS 268204-88-2 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-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((amino((2,4,6-trimethylphenyl)sulfonamido)methylene)amino)pentanoic acid.

(R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((amino((2,4,6-trimethylphenyl)sulfonamido)methylene)amino)pentanoic acid (CAS 268204-88-2), molecular formula C30H34N4O6S and molecular weight 578.68 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((amino((2,4,6-trimethylphenyl)sulfonamido)methylene)amino)pentanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 578.68 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
