Chemical Structure

3-fluoro-1-methyl-pyrazole CAS 69843-12-5 chemical structure

Description

The molecular framework of 3-fluoro-1-methyl-pyrazole (C4H9FN2) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 3-fluoro-1-methyl-pyrazole (CAS 69843-12-5), a certified reference material (molecular formula C4H9FN2, MW 104.13 g/mol) for analytical method development and quality control.

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 manufactures 3-fluoro-1-methyl-pyrazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
