Chemical Structure
Description
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (2E)-4-Oxo-4-[[2-(piperidin-1-ylsulfonyl)ethyl]-(pyridin-4-ylmethyl)amino]but-2-enoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.45 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.
(2E)-4-Oxo-4-[[2-(piperidin-1-ylsulfonyl)ethyl]-(pyridin-4-ylmethyl)amino]but-2-enoic acid (CAS 929863-40-1), molecular formula C17H23N3O5S and molecular weight 381.45 g/mol, is a CATO reference standard with documented purity and traceability.
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.
