Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Carboethoxy-3-(3,4-dimethylphenyl)propiophenone (CAS 898778-99-9) is a high-purity analytical reference standard with the molecular formula C20H22O3 and a molecular weight of 310.39 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-Carboethoxy-3-(3,4-dimethylphenyl)propiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.39 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.
CATO manufactures 2-Carboethoxy-3-(3,4-dimethylphenyl)propiophenone 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.
