Description
5-(Ethylsulfanyl)-4-thia-1,6,8-triazatricyclo[7.4.0.0^{3,7}]trideca-3(7),5,8-trien-2-one (CAS 1708079-67-7), molecular formula C11H13N3OS2 and molecular weight 267.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Ethylsulfanyl)-4-thia-1,6,8-triazatricyclo[7.4.0.0^{3,7}]trideca-3(7),5,8-trien-2-one (C11H13N3OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
CATO manufactures 5-(Ethylsulfanyl)-4-thia-1,6,8-triazatricyclo[7.4.0.0^{3,7}]trideca-3(7),5,8-trien-2-one 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.
