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)-3-(4-(pyridin-2-yl)phenyl)propanoic acid.

CATO supplies (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-(pyridin-2-yl)phenyl)propanoic acid (CAS 352525-26-9), a certified reference material (molecular formula C29H24N2O4, MW 464.51 g/mol) for analytical method development and quality control.

Structurally, (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-(pyridin-2-yl)phenyl)propanoic acid (C29H24N2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 464.51 g/mol, it falls into the moderately-high-molecular-weight range. 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.
