Chemical Structure

2-(3,4-dimethylphenyl)oxirane CAS 1855-36-3 chemical structure

Description

The occurrence of 2-(3,4-dimethylphenyl)oxirane is closely related to a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3,4-dimethylphenyl)oxirane (CAS 1855-36-3) is a high-purity analytical reference standard with the molecular formula C10H12O and a molecular weight of 148.20 g/mol.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 2-(3,4-dimethylphenyl)oxirane is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
