3-fluoro-1-methyl-1H-pyrrole-2-carboxylic acid CAS 2167489-63-4

Description

Compared with other compounds in its class, the molecular weight of 147.15 g/mol gives 3-fluoro-1-methyl-1H-pyrrole-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-fluoro-1-methyl-1H-pyrrole-2-carboxylic acid (CAS 2167489-63-4), molecular formula C6H10FNO2 and molecular weight 147.15 g/mol, is a CATO reference standard with documented purity and traceability.

3-fluoro-1-methyl-1H-pyrrole-2-carboxylic acid (C6H10FNO2) contains an amide group, a carboxylic acid 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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
