Methyl 1-(4-fluorobenzenesulfonyl)-1H-pyrrole-2-carboxylate CAS 866154-30-5 chemical structure

Description

The occurrence of Methyl 1-(4-fluorobenzenesulfonyl)-1H-pyrrole-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 1-(4-fluorobenzenesulfonyl)-1H-pyrrole-2-carboxylate (CAS 866154-30-5) is a high-purity analytical reference standard with the molecular formula C12H10FNO4S and a molecular weight of 283.28 g/mol.

Methyl 1-(4-fluorobenzenesulfonyl)-1H-pyrrole-2-carboxylate (C12H10FNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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.

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), Methyl 1-(4-fluorobenzenesulfonyl)-1H-pyrrole-2-carboxylate 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.
