Chemical Structure
Description
(4-Ethyl-3,5-dimethoxyphenyl)methanol (CAS 203579-18-4), molecular formula C11H16O3 and molecular weight 196.24 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, (4-Ethyl-3,5-dimethoxyphenyl)methanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (4-Ethyl-3,5-dimethoxyphenyl)methanol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
