Chemical Structure
Description
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.
CATO supplies (R)-1-(2-(3-((5-Methyl-2-phenyloxazol-4-yl)methoxy)phenyl)acetyl)pyrrolidine-2-carboxylic acid (CAS 799854-58-3), a certified reference material (molecular formula C24H24N2O5, MW 420.46 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (R)-1-(2-(3-((5-Methyl-2-phenyloxazol-4-yl)methoxy)phenyl)acetyl)pyrrolidine-2-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.46 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.
