Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 487.96 g/mol gives Avanafil-13C-d3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Avanafil-13C-d3 (CAS CATO-C4X-111836), molecular formula C22[13C]H23D3ClN7O3 and molecular weight 487.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Avanafil-13C-d3 (C22[13C]H23D3ClN7O3) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 487.96 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), Avanafil-13C-d3 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.
