Description
CATO supplies 5-Chloro-3-{[(4-chlorophenyl)sulfanyl]methyl}-1-methyl-4-{[(2-methylphenyl)sulfanyl]methyl}-1H-pyrazole (CAS 318234-39-8), a certified reference material (molecular formula C19H18Cl2N2S2, MW 409.40 g/mol) for analytical method development and quality control.
Structurally, 5-Chloro-3-{[(4-chlorophenyl)sulfanyl]methyl}-1-methyl-4-{[(2-methylphenyl)sulfanyl]methyl}-1H-pyrazole (C19H18Cl2N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 409.40 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.
CATO manufactures 5-Chloro-3-{[(4-chlorophenyl)sulfanyl]methyl}-1-methyl-4-{[(2-methylphenyl)sulfanyl]methyl}-1H-pyrazole 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.
