Chemical Structure

n-Cyclopropyl-5-(furan-2-yl)-1,2-oxazole-3-carboxamide CAS 135401-63-7 chemical structure

Description

The occurrence of n-Cyclopropyl-5-(furan-2-yl)-1,2-oxazole-3-carboxamide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

n-Cyclopropyl-5-(furan-2-yl)-1,2-oxazole-3-carboxamide (CAS 135401-63-7), molecular formula C11H10N2O3 and molecular weight 218.21 g/mol, is a CATO reference standard with documented purity and traceability.

n-Cyclopropyl-5-(furan-2-yl)-1,2-oxazole-3-carboxamide (C11H10N2O3) 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).

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.
