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 N-({1-[(4-Fluorophenyl)sulfonyl]piperidin-3-yl}carbonyl)-L-valine (CAS 956970-52-8), a certified reference material (molecular formula C17H23FN2O5S, MW 386.44 g/mol) for analytical method development and quality control.
The molecular framework of N-({1-[(4-Fluorophenyl)sulfonyl]piperidin-3-yl}carbonyl)-L-valine (C17H23FN2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
