Chemical Structure
Description
The occurrence of (2E)-3-(Dimethylamino)-2-[(E)-3-(2-methylphenoxy)benzoyl]prop-2-enenitrile is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2E)-3-(Dimethylamino)-2-[(E)-3-(2-methylphenoxy)benzoyl]prop-2-enenitrile (CAS 1164538-51-5), molecular formula C19H18N2O2 and molecular weight 306.36 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-3-(Dimethylamino)-2-[(E)-3-(2-methylphenoxy)benzoyl]prop-2-enenitrile (C19H18N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (2E)-3-(Dimethylamino)-2-[(E)-3-(2-methylphenoxy)benzoyl]prop-2-enenitrile 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.
