Chemical Structure

2-(tert-Butyl)-2H-naphtho[2,3-f]isoindole-5,10-dione CAS 92763-82-1 chemical structure

Description

The occurrence of 2-(tert-Butyl)-2H-naphtho[2,3-f]isoindole-5,10-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(tert-Butyl)-2H-naphtho[2,3-f]isoindole-5,10-dione (CAS 92763-82-1), molecular formula C20H17NO2 and molecular weight 303.35 g/mol, is a CATO reference standard with documented purity and traceability.

2-(tert-Butyl)-2H-naphtho[2,3-f]isoindole-5,10-dione (C20H17NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
