Chemical Structure
Description
8-Thia-4,6-diazatricyclo[7.4.0.0,2,7]trideca-1(9),2(7),5,10,12-pentaen-3-one (CAS 18774-49-7), molecular formula C10H6N2OS and molecular weight 202.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 8-Thia-4,6-diazatricyclo[7.4.0.0,2,7]trideca-1(9),2(7),5,10,12-pentaen-3-one (C10H6N2OS) 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
