Chemical Structure
Description
n-Cyclopropyl-2-nitrobenzamide (CAS 88229-20-3), molecular formula C10H10N2O3 and molecular weight 206.20 g/mol, is a CATO reference standard with documented purity and traceability.
n-Cyclopropyl-2-nitrobenzamide (C10H10N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).
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.
