255901-50-9 3,4-(2,2-Dimethylpropylenedioxy)thiophene MFCD08705268 3,4-Dihydro-3,3-dimethyl-2H-thieno[3,4-b-1,4]dioxepin, EDOT analog CAS 255901-50-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 255901-50-9 3,4-(2,2-Dimethylpropylenedioxy)thiophene MFCD08705268 3,4-Dihydro-3,3-dimethyl-2H-thieno[3,4-b-1,4]dioxepin, EDOT analog.

255901-50-9 3,4-(2,2-Dimethylpropylenedioxy)thiophene MFCD08705268 3,4-Dihydro-3,3-dimethyl-2H-thieno[3,4-b-1,4]dioxepin, EDOT analog (CAS 255901-50-9) is a high-purity analytical reference standard with the molecular formula C9H16O2S and a molecular weight of 188.29 g/mol.

Based on its molecular formula C9H16O2S, 255901-50-9 3,4-(2,2-Dimethylpropylenedioxy)thiophene MFCD08705268 3,4-Dihydro-3,3-dimethyl-2H-thieno[3,4-b-1,4]dioxepin, EDOT analog contains a sulfone group, 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 188.29 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.
