Chemical Structure
Description
2-Methyl-5-(pyrrolidin-1-ylsulfonyl)furan-3-carboxylic acid (CAS 306936-43-6) is a high-purity analytical reference standard with the molecular formula C10H13NO5S and a molecular weight of 259.28 g/mol.
2-Methyl-5-(pyrrolidin-1-ylsulfonyl)furan-3-carboxylic acid (C10H13NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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-Methyl-5-(pyrrolidin-1-ylsulfonyl)furan-3-carboxylic acid 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.
