Chemical Structure
Description
(17β)-13-Ethyl-3-methoxygona-1,3,5(10),15-tetraen-17-ol (CAS 59126-63-5) is a high-purity analytical reference standard with the molecular formula C20H26O2 and a molecular weight of 298.42 g/mol.
(17β)-13-Ethyl-3-methoxygona-1,3,5(10),15-tetraen-17-ol (C20H26O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (17β)-13-Ethyl-3-methoxygona-1,3,5(10),15-tetraen-17-ol 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.
