Description
Compared with other compounds in its class, the molecular weight of 304.47 g/mol gives 4,5β-Dihydro Norethandrolone (1.0mg/ml in Acetonitrile) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,5β-Dihydro Norethandrolone (1.0mg/ml in Acetonitrile) (CAS 31658-44-3) is a high-purity analytical reference standard with the molecular formula C20H32O2 and a molecular weight of 304.47 g/mol.
4,5β-Dihydro Norethandrolone (1.0mg/ml in Acetonitrile) (C20H32O2) 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.
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 4,5β-Dihydro Norethandrolone (1.0mg/ml in Acetonitrile) 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.
