Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 162.15 g/mol gives 2-Benzoxazolecarboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Benzoxazolecarboxamide (CAS 3313-38-0), a certified reference material (molecular formula C8H6N2O2, MW 162.15 g/mol) for analytical method development and quality control.
Structurally, 2-Benzoxazolecarboxamide (C8H6N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 162.15 g/mol, it falls into the medium-molecular-weight range. 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.
