Description
(5S,18S)-1,22-Diamino-7,16-dioxo-6,8,15,17-tetraazadocosane-5,18-dicarboxylic Acid (CAS 1417789-80-0), molecular formula C20H40N6O6 and molecular weight 460.57 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5S,18S)-1,22-Diamino-7,16-dioxo-6,8,15,17-tetraazadocosane-5,18-dicarboxylic Acid (C20H40N6O6) is characterized by a steroid 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
