3,5-Dichloroanisole CAS 33719-74-3 chemical structure

Description

As a certified reference material (CRM), 3,5-Dichloroanisole 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.

3,5-Dichloroanisole (CAS 33719-74-3) is a high-purity analytical reference standard with the molecular formula C7H6Cl2O and a molecular weight of 177.03 g/mol.

3,5-Dichloroanisole (C7H6Cl2O) contains a hydroxyl group, an ether linkage, 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).

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.
