6-(Methylsulfanyl)-4,5,7,9,13-pentaazapentacyclo[11.8.0.0^{3,11}.0^{4,8}.0^{16,21}]henicosa-3(11),5,7,9,16(21),17,19-heptaen-12-one (CAS 339012-07-6), molecular formula C17H15N5OS and molecular weight 337.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-(Methylsulfanyl)-4,5,7,9,13-pentaazapentacyclo[11.8.0.0^{3,11}.0^{4,8}.0^{16,21}]henicosa-3(11),5,7,9,16(21),17,19-heptaen-12-one (C17H15N5OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
