Chemical Structure
Description
The occurrence of Testosterone-16,16,17-D3 is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Testosterone-16,16,17-D3 (CAS 77546-39-5), a certified reference material (molecular formula C19H25D3O2, MW 291.44 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, Testosterone-16,16,17-D3 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.44 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).
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 Testosterone-16,16,17-D3 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.
