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 1-(Difluoromethyl)-1h-pyrazole.
CATO supplies 1-(Difluoromethyl)-1h-pyrazole (CAS 908014-77-7), a certified reference material (molecular formula C4H4F2N2, MW 118.08 g/mol) for analytical method development and quality control.
Structurally, 1-(Difluoromethyl)-1h-pyrazole (C4H4F2N2) contains a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 118.08 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 1-(Difluoromethyl)-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.
