Chemical Structure
Description
N-Desmethyl-N-benzyl Sildenafil (CAS 1446089-82-2), molecular formula C28H34N6O4S and molecular weight 550.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-Desmethyl-N-benzyl Sildenafil (C28H34N6O4S) is characterized by a steroid core, an amide group, a sulfone 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.
CATO manufactures N-Desmethyl-N-benzyl Sildenafil 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.
