Chemical Structure
Description
2-(4-Ethyl-2,3-dioxopiperazine-1-carboxamido)-2-(4-hydroxyphenyl)acetic Acid (CAS 79868-75-0), molecular formula C15H17N3O6 and molecular weight 335.31 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 2-(4-Ethyl-2,3-dioxopiperazine-1-carboxamido)-2-(4-hydroxyphenyl)acetic Acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.31 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.
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.
