Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, Testosterone phenylacetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Testosterone phenylacetate (CAS 5704-03-0), molecular formula C27H34O3 and molecular weight 406.56 g/mol, is a CATO reference standard with documented purity and traceability.
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 Testosterone phenylacetate 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.
