(E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)(methoxy)amine CAS 321553-46-2

Description

(E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)(methoxy)amine (CAS 321553-46-2) is a high-purity analytical reference standard with the molecular formula C13H11ClF3N3OS and a molecular weight of 349.76 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (E)-({5-[(4-chlorophenyl)sulfanyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl}methylidene)(methoxy)amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.76 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)(methoxy)amine 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.
