Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (E)-4-(hexadecylamino)-4-oxobut-2-enoic acid (CAS 100581-95-1), a certified reference material (molecular formula C20H37NO3, MW 339.51 g/mol) for analytical method development and quality control.
The molecular framework of (E)-4-(hexadecylamino)-4-oxobut-2-enoic acid (C20H37NO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
CATO manufactures (E)-4-(hexadecylamino)-4-oxobut-2-enoic acid 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.
