Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)amino 2,2-dichloroacetate.
CATO supplies (E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)amino 2,2-dichloroacetate (CAS 321553-42-8), a certified reference material (molecular formula C14H9Cl3F3N3O2S, MW 446.66 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)amino 2,2-dichloroacetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 446.66 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.
As a certified reference material (CRM), (E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)amino 2,2-dichloroacetate 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.
