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 1-(1-(((9H-Fluoren-9-yl)methoxy)carbonyl)pyrrolidin-3-yl)-5-(difluoromethyl)-1H-1,2,3-triazole-4-carboxylic acid (CAS 2138367-00-5), a certified reference material (molecular formula C23H20F2N4O4, MW 454.43 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(1-(((9H-Fluoren-9-yl)methoxy)carbonyl)pyrrolidin-3-yl)-5-(difluoromethyl)-1H-1,2,3-triazole-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 454.43 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.
