Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 168.19 g/mol gives 2-Ethoxy-6-(hydroxymethyl)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Ethoxy-6-(hydroxymethyl)phenol (CAS 83742-40-9), molecular formula C9H12O3 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Ethoxy-6-(hydroxymethyl)phenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
