Chemical Structure

(E)-4-(4-nitrostyryl)-8-(trifluoromethoxy)-2,3-dihydrothieno[3,2-c]quinoline CAS 866133-32-6 chemical structure

Description

As a certified reference material (CRM), (E)-4-(4-nitrostyryl)-8-(trifluoromethoxy)-2,3-dihydrothieno[3,2-c]quinoline 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.

(E)-4-(4-nitrostyryl)-8-(trifluoromethoxy)-2,3-dihydrothieno[3,2-c]quinoline (CAS 866133-32-6), molecular formula C20H13F3N2O3S and molecular weight 418.39 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, (E)-4-(4-nitrostyryl)-8-(trifluoromethoxy)-2,3-dihydrothieno[3,2-c]quinoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
