Chemical Structure

4-Methyl-1-phenyl-7-oxabicyclo[4.1.0]heptane CAS 21592-66-5 chemical structure

Description

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.

4-Methyl-1-phenyl-7-oxabicyclo[4.1.0]heptane (CAS 21592-66-5), molecular formula C13H16O and molecular weight 188.27 g/mol, is a CATO reference standard with documented purity and traceability.

4-Methyl-1-phenyl-7-oxabicyclo[4.1.0]heptane (C13H16O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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.
