Chemical Structure
Description
Owing to a nitrile group, fluorine substitution, an aromatic ring system, 3-(1,1-Difluoroethyl)pyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 3-(1,1-Difluoroethyl)pyridine (CAS 114468-03-0), a certified reference material (molecular formula C7H7F2N, MW 143.13 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.
As a certified reference material (CRM), 3-(1,1-Difluoroethyl)pyridine 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.
