Description

Compared with other compounds in its class, the molecular weight of 232.28 g/mol gives 5-(4-Fluorophenyl)-4,5-dihydrothieno[2,3-d]pyridazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-(4-Fluorophenyl)-4,5-dihydrothieno[2,3-d]pyridazine (CAS 303145-59-7), a certified reference material (molecular formula C12H9FN2S, MW 232.28 g/mol) for analytical method development and quality control.

5-(4-Fluorophenyl)-4,5-dihydrothieno[2,3-d]pyridazine (C12H9FN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine 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. 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.

As a certified reference material (CRM), 5-(4-Fluorophenyl)-4,5-dihydrothieno[2,3-d]pyridazine 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.
