Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 177.03 g/mol gives 2,6-Dichloro-3-methylphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,6-Dichloro-3-methylphenol (CAS 13481-70-4), molecular formula C7H6Cl2O and molecular weight 177.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Dichloro-3-methylphenol (C7H6Cl2O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
