Description

The occurrence of 493-09-4 ZC5YP57PSW 1,4-Benzodioxan 1,4-Benzodioxan (8CI) 1,4-Benzodioxane 1,4-Benzodioxin, 2,3-dihydro- AI3-05084 Benzene, 1,2-(1,2-ethanediylbis(oxy))- 2,3-Dihydro-1,4-benzodioxin EINECS 207-775-6 Ethylene o-phenylene dioxide 1,2-(Ethylenedioxy)benzene NSC 406705 Pyrocatechol ethylene ether UNII-ZC5YP57PSW is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

493-09-4 ZC5YP57PSW 1,4-Benzodioxan 1,4-Benzodioxan (8CI) 1,4-Benzodioxane 1,4-Benzodioxin, 2,3-dihydro- AI3-05084 Benzene, 1,2-(1,2-ethanediylbis(oxy))- 2,3-Dihydro-1,4-benzodioxin EINECS 207-775-6 Ethylene o-phenylene dioxide 1,2-(Ethylenedioxy)benzene NSC 406705 Pyrocatechol ethylene ether UNII-ZC5YP57PSW (CAS 493-09-4) is a high-purity analytical reference standard with the molecular formula C8H14O2 and a molecular weight of 142.20 g/mol.

Based on its molecular formula C8H14O2, 493-09-4 ZC5YP57PSW 1,4-Benzodioxan 1,4-Benzodioxan (8CI) 1,4-Benzodioxane 1,4-Benzodioxin, 2,3-dihydro- AI3-05084 Benzene, 1,2-(1,2-ethanediylbis(oxy))- 2,3-Dihydro-1,4-benzodioxin EINECS 207-775-6 Ethylene o-phenylene dioxide 1,2-(Ethylenedioxy)benzene NSC 406705 Pyrocatechol ethylene ether UNII-ZC5YP57PSW contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 142.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
