Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 334.88 g/mol gives 4-Chlorodehydromethyltestosterone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chlorodehydromethyltestosterone (CAS 2446-23-3), molecular formula C20H27ClO2 and molecular weight 334.88 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chlorodehydromethyltestosterone (C20H27ClO2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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-Chlorodehydromethyltestosterone 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.
