Description

3-[(2-Ethoxy-3,4-dioxocyclobutyl)amino]-2-hydroxy-N,N-dimethylbenzamide 919349-40-9 (CAS 919349-40-9), molecular formula C15H18N2O5 and molecular weight 306.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-[(2-Ethoxy-3,4-dioxocyclobutyl)amino]-2-hydroxy-N,N-dimethylbenzamide 919349-40-9 (C15H18N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. 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.

CATO manufactures 3-[(2-Ethoxy-3,4-dioxocyclobutyl)amino]-2-hydroxy-N,N-dimethylbenzamide 919349-40-9 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
