(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(pyridin-4-yl)acetic acid CAS 1228565-81-8

Description

The occurrence of (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(pyridin-4-yl)acetic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(pyridin-4-yl)acetic acid (CAS 1228565-81-8) is a high-purity analytical reference standard with the molecular formula C22H18N2O4 and a molecular weight of 374.39 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(pyridin-4-yl)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.39 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
