Chemical Structure
Description
1-{[5-(chloromethyl)-2-furyl]sulfonyl}pyrrolidine (C9H12ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1-{[5-(chloromethyl)-2-furyl]sulfonyl}pyrrolidine (CAS 1110820-18-2) is a high-purity analytical reference standard with the molecular formula C9H12ClNO3S and a molecular weight of 249.71 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.
