(2E)-2-[(E)-2-(3,5-Dichlorophenoxy)pyridine-3-carbonyl]-3-(dimethylamino)prop-2-enenitrile CAS 136257-60-8 chemical structure

Description

The occurrence of (2E)-2-[(E)-2-(3,5-Dichlorophenoxy)pyridine-3-carbonyl]-3-(dimethylamino)prop-2-enenitrile is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2E)-2-[(E)-2-(3,5-Dichlorophenoxy)pyridine-3-carbonyl]-3-(dimethylamino)prop-2-enenitrile (CAS 136257-60-8), a certified reference material (molecular formula C17H13Cl2N3O2, MW 362.21 g/mol) for analytical method development and quality control.

(2E)-2-[(E)-2-(3,5-Dichlorophenoxy)pyridine-3-carbonyl]-3-(dimethylamino)prop-2-enenitrile (C17H13Cl2N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), (2E)-2-[(E)-2-(3,5-Dichlorophenoxy)pyridine-3-carbonyl]-3-(dimethylamino)prop-2-enenitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
