Chemical Structure
Description
As a certified reference material (CRM), 2-Chloro-5-fluoro-3-methylphenol 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-5-fluoro-3-methylphenol (CAS 1805455-85-9) is a high-purity analytical reference standard with the molecular formula C7H6ClFO and a molecular weight of 160.57 g/mol.
2-Chloro-5-fluoro-3-methylphenol (C7H6ClFO) 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 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).
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.
