Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 135.12 g/mol gives Benzoxazol-7-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benzoxazol-7-ol (CAS 94242-04-3) is a high-purity analytical reference standard with the molecular formula C7H5NO2 and a molecular weight of 135.12 g/mol.
Based on its molecular formula C7H5NO2, Benzoxazol-7-ol contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 135.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
