5-(difluoromethoxy)-1H-pyrazol-3-amine CAS 1160822-72-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(difluoromethoxy)-1H-pyrazol-3-amine.

5-(difluoromethoxy)-1H-pyrazol-3-amine (CAS 1160822-72-9), molecular formula C4H9F2N3O and molecular weight 153.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(difluoromethoxy)-1H-pyrazol-3-amine (C4H9F2N3O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine 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.

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), 5-(difluoromethoxy)-1H-pyrazol-3-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.
