Chemical Structure
Description
The occurrence of (R)-2-Methyl-N-(1-(naphthalen-1-yl)ethyl)-5-nitrobenzamide 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.
CATO supplies (R)-2-Methyl-N-(1-(naphthalen-1-yl)ethyl)-5-nitrobenzamide (CAS 1093070-15-5), a certified reference material (molecular formula C20H18N2O3, MW 334.37 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (R)-2-Methyl-N-(1-(naphthalen-1-yl)ethyl)-5-nitrobenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
