6-[(4-Ethyl-5-{[(4-methylphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one CAS 692737-13-6

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.

6-[(4-Ethyl-5-{[(4-methylphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one (CAS 692737-13-6), molecular formula C23H23N5O2S and molecular weight 433.53 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, 6-[(4-Ethyl-5-{[(4-methylphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 433.53 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).

As a certified reference material (CRM), 6-[(4-Ethyl-5-{[(4-methylphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one 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.
