Chemical Structure
Description
10-(2-Ethylhexyl)-10H-phenothiazine (CAS 264264-00-8), molecular formula C20H25NS and molecular weight 311.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 10-(2-Ethylhexyl)-10H-phenothiazine (C20H25NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.
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.
