Chemical Structure

1,1,3,3-Tetramethyl-1,3-dihydroisobenzofuran CAS 113710-83-1 chemical structure

Description

1,1,3,3-Tetramethyl-1,3-dihydroisobenzofuran (CAS 113710-83-1), molecular formula C12H16O and molecular weight 176.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H16O, 1,1,3,3-Tetramethyl-1,3-dihydroisobenzofuran contains a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 176.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
