1,4-Difluoro-2,3-dimethylbenzene CAS 1736-90-9 chemical structure

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.

1,4-Difluoro-2,3-dimethylbenzene (CAS 1736-90-9) is a high-purity analytical reference standard with the molecular formula C8H8F2 and a molecular weight of 142.15 g/mol.

1,4-Difluoro-2,3-dimethylbenzene (C8H8F2) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

CATO manufactures 1,4-Difluoro-2,3-dimethylbenzene 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.
