2-Methyl-5-(3-(trifluoromethyl)-1H-pyrazol-5-yl)furan-3-sulfonyl chloride CAS 1287752-71-9

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.

2-Methyl-5-(3-(trifluoromethyl)-1H-pyrazol-5-yl)furan-3-sulfonyl chloride (CAS 1287752-71-9), molecular formula C9H6ClF3N2O3S and molecular weight 314.67 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Methyl-5-(3-(trifluoromethyl)-1H-pyrazol-5-yl)furan-3-sulfonyl chloride (C9H6ClF3N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 2-Methyl-5-(3-(trifluoromethyl)-1H-pyrazol-5-yl)furan-3-sulfonyl chloride 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.
