Chemical Structure

N-(2,6-Dichloroisonicotinoyl)-N'-(4-fluorophenyl)thiourea CAS 646456-16-8 chemical structure

Description

The occurrence of N-(2,6-Dichloroisonicotinoyl)-N'-(4-fluorophenyl)thiourea is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-(2,6-Dichloroisonicotinoyl)-N'-(4-fluorophenyl)thiourea (CAS 646456-16-8) is a high-purity analytical reference standard with the molecular formula C13H8Cl2FN3OS and a molecular weight of 344.19 g/mol.

N-(2,6-Dichloroisonicotinoyl)-N'-(4-fluorophenyl)thiourea (C13H8Cl2FN3OS) contains a nitrogen-containing heterocyclic scaffold, 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).

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), N-(2,6-Dichloroisonicotinoyl)-N'-(4-fluorophenyl)thiourea 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.
