Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 655.65 g/mol gives 15alpha-Hydroxy Testosterone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
15alpha-Hydroxy Testosterone (CAS 2226-70-2) is a high-purity analytical reference standard with the molecular formula C30H43F10NO3 and a molecular weight of 655.65 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 15alpha-Hydroxy Testosterone is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 655.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 15alpha-Hydroxy Testosterone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
