(5-Chloro-3-(difluoromethyl)-1-methyl-1H-pyrazol-4-yl)methanol CAS 447401-95-8 chemical structure

Description

The occurrence of (5-Chloro-3-(difluoromethyl)-1-methyl-1H-pyrazol-4-yl)methanol is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (5-Chloro-3-(difluoromethyl)-1-methyl-1H-pyrazol-4-yl)methanol (CAS 447401-95-8), a certified reference material (molecular formula C6H7ClF2N2O, MW 196.58 g/mol) for analytical method development and quality control.

The molecular framework of (5-Chloro-3-(difluoromethyl)-1-methyl-1H-pyrazol-4-yl)methanol (C6H7ClF2N2O) is characterized by 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), (5-Chloro-3-(difluoromethyl)-1-methyl-1H-pyrazol-4-yl)methanol 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.
