(2E)-3-(4-Chlorophenyl)-2-[5-(2-fluorobenzoyl)thiophen-2-yl]prop-2-enenitrile CAS 338966-82-8

Description

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.

(2E)-3-(4-Chlorophenyl)-2-[5-(2-fluorobenzoyl)thiophen-2-yl]prop-2-enenitrile (CAS 338966-82-8) is a high-purity analytical reference standard with the molecular formula C20H11ClFNOS and a molecular weight of 367.82 g/mol.

(2E)-3-(4-Chlorophenyl)-2-[5-(2-fluorobenzoyl)thiophen-2-yl]prop-2-enenitrile (C20H11ClFNOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

As a certified reference material (CRM), (2E)-3-(4-Chlorophenyl)-2-[5-(2-fluorobenzoyl)thiophen-2-yl]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.
