Chemical Structure

3,6-Dimethylbenzo[d]isoxazole CAS 29505-13-3 chemical structure

Description

Structurally, 3,6-Dimethylbenzo[d]isoxazole (C9H9NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 147.17 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

3,6-Dimethylbenzo[d]isoxazole (CAS 29505-13-3) is a high-purity analytical reference standard with the molecular formula C9H9NO and a molecular weight of 147.17 g/mol.

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.
