Chemical Structure

4894-23-9 Isoxazole, 4,5-dihydro-3,5-diphenyl- 4,5-Dihydro-3,5-diphenylisoxazole CAS 4894-23-9 chemical structure

Description

4894-23-9 Isoxazole, 4,5-dihydro-3,5-diphenyl- 4,5-Dihydro-3,5-diphenylisoxazole (C15H13NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

4894-23-9 Isoxazole, 4,5-dihydro-3,5-diphenyl- 4,5-Dihydro-3,5-diphenylisoxazole (CAS 4894-23-9) is a high-purity analytical reference standard with the molecular formula C15H13NO and a molecular weight of 223.27 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.
