Chemical Structure
Description
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.
(2S,3S)-1,4-Dichlorobutane-diol Sulfate (CAS 190850-76-1) is a high-purity analytical reference standard with the molecular formula C4H6Cl2O4S and a molecular weight of 221.06 g/mol.
(2S,3S)-1,4-Dichlorobutane-diol Sulfate (C4H6Cl2O4S) contains a carbohydrate-derived structure, a sulfone group, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (2S,3S)-1,4-Dichlorobutane-diol Sulfate 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.
