Chemical Structure

methyl 4-fluoro-3,5-dimethyl-1H-pyrrole-2-carboxylate CAS 2103864-91-9 chemical structure

Description

As a certified reference material (CRM), methyl 4-fluoro-3,5-dimethyl-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.

methyl 4-fluoro-3,5-dimethyl-1H-pyrrole-2-carboxylate (CAS 2103864-91-9) is a high-purity analytical reference standard with the molecular formula C8H10FNO2 and a molecular weight of 171.17 g/mol.

methyl 4-fluoro-3,5-dimethyl-1H-pyrrole-2-carboxylate (C8H10FNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

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.
