Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Chloro-1,1-dioxidotetrahydrothiophen-3-yl acetate (CAS 75754-25-5) is a high-purity analytical reference standard with the molecular formula C6H9ClO4S and a molecular weight of 212.65 g/mol.
The molecular framework of 4-Chloro-1,1-dioxidotetrahydrothiophen-3-yl acetate (C6H9ClO4S) 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.
As a certified reference material (CRM), 4-Chloro-1,1-dioxidotetrahydrothiophen-3-yl acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
