4-(Difluoromethyl)toluene CAS 66865-75-6 chemical structure

Description

CATO supplies 4-(Difluoromethyl)toluene (CAS 66865-75-6), a certified reference material (molecular formula C8H8F2, MW 142.15 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H8F2, 4-(Difluoromethyl)toluene contains fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 142.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 4-(Difluoromethyl)toluene 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.
