Potassium (E)-2-[(4-Ethoxy-4-oxobutan-2-ylidene)amino]-2-phenylacetate CAS 65749-39-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium (E)-2-[(4-Ethoxy-4-oxobutan-2-ylidene)amino]-2-phenylacetate.

Potassium (E)-2-[(4-Ethoxy-4-oxobutan-2-ylidene)amino]-2-phenylacetate (CAS 65749-39-5), molecular formula C14H16NO4K and molecular weight 301.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Potassium (E)-2-[(4-Ethoxy-4-oxobutan-2-ylidene)amino]-2-phenylacetate (C14H16NO4K) is characterized by a nitrogen-containing heterocyclic scaffold, 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 Potassium (E)-2-[(4-Ethoxy-4-oxobutan-2-ylidene)amino]-2-phenylacetate 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.
