The occurrence of (2,5-dioxopyrrolidin-1-yl)dimethylsulfonium chloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2,5-dioxopyrrolidin-1-yl)dimethylsulfonium chloride (CAS 39095-38-0) is a high-purity analytical reference standard with the molecular formula C4H4ClNO2C2H6S and a molecular weight of 195.66 g/mol.
The molecular framework of (2,5-dioxopyrrolidin-1-yl)dimethylsulfonium chloride (C4H4ClNO2C2H6S) is characterized by an amide group, 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 protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), (2,5-dioxopyrrolidin-1-yl)dimethylsulfonium chloride 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.
