Chemical Structure
Description
As a certified reference material (CRM), 2-(Difluoromethyl)-8-fluoronaphthalene 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.
CATO supplies 2-(Difluoromethyl)-8-fluoronaphthalene (CAS 1261532-30-2), a certified reference material (molecular formula C11H7F3, MW 196.17 g/mol) for analytical method development and quality control.
Structurally, 2-(Difluoromethyl)-8-fluoronaphthalene (C11H7F3) contains fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 196.17 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
