As a certified reference material (CRM), 2-Chloro-4,6-dimethylphenol 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.
2-Chloro-4,6-dimethylphenol (CAS 6641-04-9), molecular formula C8H9ClO and molecular weight 156.61 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-4,6-dimethylphenol (C8H9ClO) 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.
