4-Chloro-2-ethyl-1-fluorobenzene CAS 1369889-05-3 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.

4-Chloro-2-ethyl-1-fluorobenzene (CAS 1369889-05-3), molecular formula C8H8ClF and molecular weight 158.60 g/mol, is a CATO reference standard with documented purity and traceability.

4-Chloro-2-ethyl-1-fluorobenzene (C8H8ClF) contains fluorine/chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 4-Chloro-2-ethyl-1-fluorobenzene 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.
