3-Benzyl-7-ethyl-2-mercapto-5,6,7,8-tetrahydro-3H-9-thia-1,3,7-triaza-fluoren-4-one CAS 352446-15-2

Description

3-Benzyl-7-ethyl-2-mercapto-5,6,7,8-tetrahydro-3H-9-thia-1,3,7-triaza-fluoren-4-one (CAS 352446-15-2) is a high-purity analytical reference standard with the molecular formula C18H19N3OS2 and a molecular weight of 357.49 g/mol.

3-Benzyl-7-ethyl-2-mercapto-5,6,7,8-tetrahydro-3H-9-thia-1,3,7-triaza-fluoren-4-one (C18H19N3OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
