Chemical Structure
Description
3-((2,3-Dihydrothieno[3,4-b][1,4]dioxin-2-yl)methoxy)propanoic acid (C10H12O5S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).
3-((2,3-Dihydrothieno[3,4-b][1,4]dioxin-2-yl)methoxy)propanoic acid (CAS 853799-71-0) is a high-purity analytical reference standard with the molecular formula C10H12O5S and a molecular weight of 244.26 g/mol.
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.
