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 19039-94-2 3-Buten-2-one, 4-(3,4,5-trimethoxyphenyl)-, (3E)- CTK0A2356.
19039-94-2 3-Buten-2-one, 4-(3,4,5-trimethoxyphenyl)-, (3E)- CTK0A2356 (CAS 19039-94-2), molecular formula C13H16O4 and molecular weight 236.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 19039-94-2 3-Buten-2-one, 4-(3,4,5-trimethoxyphenyl)-, (3E)- CTK0A2356 (C13H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 19039-94-2 3-Buten-2-one, 4-(3,4,5-trimethoxyphenyl)-, (3E)- CTK0A2356 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.
