Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, 4-{[(4-bromophenyl)sulfanyl]methyl}-5-chloro-1-methyl-3-{[(4-methylphenyl)sulfanyl]methyl}-1H-pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 453.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4-{[(4-bromophenyl)sulfanyl]methyl}-5-chloro-1-methyl-3-{[(4-methylphenyl)sulfanyl]methyl}-1H-pyrazole (CAS 318248-64-5), molecular formula C19H18BrClN2S2 and molecular weight 453.85 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-{[(4-bromophenyl)sulfanyl]methyl}-5-chloro-1-methyl-3-{[(4-methylphenyl)sulfanyl]methyl}-1H-pyrazole 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.
