Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 207.05 g/mol gives (2,6-Dichloro-3-methoxyphenyl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2,6-Dichloro-3-methoxyphenyl)methanol (CAS 160646-99-1), molecular formula C8H8Cl2O2 and molecular weight 207.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2,6-Dichloro-3-methoxyphenyl)methanol (C8H8Cl2O2) is characterized by a carboxylic acid group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
