3,5-difluoropyridine CAS 71902-33-5 chemical structure

Description

CATO supplies 3,5-difluoropyridine (CAS 71902-33-5), a certified reference material (molecular formula C5H9F2N, MW 121.13 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H9F2N, 3,5-difluoropyridine contains fluorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 121.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 3,5-difluoropyridine 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.
