N'3-[3,5-di(trifluoromethyl)phenyl]-5-chloro-1-methyl-1H-pyrazole-3-carbohydrazide CAS 648408-73-5 chemical structure

Description

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.

CATO supplies N'3-[3,5-di(trifluoromethyl)phenyl]-5-chloro-1-methyl-1H-pyrazole-3-carbohydrazide (CAS 648408-73-5), a certified reference material (molecular formula C13H9ClF6N4O, MW 386.68 g/mol) for analytical method development and quality control.

The molecular framework of N'3-[3,5-di(trifluoromethyl)phenyl]-5-chloro-1-methyl-1H-pyrazole-3-carbohydrazide (C13H9ClF6N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), N'3-[3,5-di(trifluoromethyl)phenyl]-5-chloro-1-methyl-1H-pyrazole-3-carbohydrazide 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.
