The molecular framework of 2,3-Dihydro-benzo[1,4]dioxine-6-sulfonyl chloride 2,3-dihydro-1,4-benzodioxine-6-sulfonyl chloride 2,3-dihydro-1,4-benzodioxine-6-sulfonylchloride 2,3-dihydro-1,4-benzodioxine-6-sulphonyl chloride 2,3-dihydro-1,4-benzodioxine-6-sulphonylchloride 2,3-dihydro-benzo[1,4]dioxine-6-sulfonylchloride 6-chlorosulfonyl-benzo-1,4-dioxane 63758-12-3 (C8H13ClO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
