4-Chloro-5-iodo-o-xylene CAS 1208078-25-4

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-5-iodo-o-xylene (CAS 1208078-25-4), molecular formula C7H2Cl2F2O and molecular weight 210.99 g/mol, is a CATO reference standard with documented purity and traceability.

4-Chloro-5-iodo-o-xylene (C7H2Cl2F2O) contains a hydroxyl group, an ether linkage, 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).

As a certified reference material (CRM), 4-Chloro-5-iodo-o-xylene 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.
