(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-amino-2-methyl-4-oxobutanoic acid CAS 1403590-49-7

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)-4-amino-2-methyl-4-oxobutanoic acid.

CATO supplies (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-amino-2-methyl-4-oxobutanoic acid (CAS 1403590-49-7), a certified reference material (molecular formula C20H20N2O5, MW 368.38 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-amino-2-methyl-4-oxobutanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
