(R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-(((tert-butoxycarbonyl)amino)methyl)phenyl)propanoic acid CAS 268731-06-2 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)-3-(4-(((tert-butoxycarbonyl)amino)methyl)phenyl)propanoic acid.

(R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-(((tert-butoxycarbonyl)amino)methyl)phenyl)propanoic acid (CAS 268731-06-2) is a high-purity analytical reference standard with the molecular formula C30H32N2O6 and a molecular weight of 516.58 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-(((tert-butoxycarbonyl)amino)methyl)phenyl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 516.58 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.
