Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-[(4-Ethyl-5-{[(4-methoxyphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one.
CATO supplies 6-[(4-Ethyl-5-{[(4-methoxyphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one (CAS 866136-78-9), a certified reference material (molecular formula C23H23N5O3S, MW 449.53 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, 6-[(4-Ethyl-5-{[(4-methoxyphenyl)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 449.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 6-[(4-Ethyl-5-{[(4-methoxyphenyl)methyl]sulfanyl}-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
