The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 5-[(4-Chlorophenyl)sulfanyl]-4-{[(2,6-dichlorophenyl)methoxy]methyl}-1-methyl-3-phenyl-1H-pyrazole (CAS 321538-27-6), a certified reference material (molecular formula C24H19Cl3N2OS, MW 489.84 g/mol) for analytical method development and quality control.
Structurally, 5-[(4-Chlorophenyl)sulfanyl]-4-{[(2,6-dichlorophenyl)methoxy]methyl}-1-methyl-3-phenyl-1H-pyrazole (C24H19Cl3N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 489.84 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
