Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Nitroso Tadalafil-D3.
N-Nitroso Tadalafil-D3 (CAS CATO-C4X-1087179), molecular formula C22H15D3N4O5 and molecular weight 421.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-Nitroso Tadalafil-D3 (C22H15D3N4O5) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), N-Nitroso Tadalafil-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.
