Chemical Structure
Description
As a certified reference material (CRM), Methyl 4-[(4-methylphenyl)sulfanyl]-6-oxo-1-[3-(trifluoromethyl)phenyl]-1,6-dihydropyridazine-3-carboxylate 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.
CATO supplies Methyl 4-[(4-methylphenyl)sulfanyl]-6-oxo-1-[3-(trifluoromethyl)phenyl]-1,6-dihydropyridazine-3-carboxylate (CAS 338395-80-5), a certified reference material (molecular formula C20H15F3N2O3S, MW 420.40 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Methyl 4-[(4-methylphenyl)sulfanyl]-6-oxo-1-[3-(trifluoromethyl)phenyl]-1,6-dihydropyridazine-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
