Chemical Structure
Description
4-Fluoro-1H-pyrrole-2-carboxamide (CAS 915230-16-9), molecular formula C5H5FN2O and molecular weight 128.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Fluoro-1H-pyrrole-2-carboxamide (C5H5FN2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 128.10 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 4-Fluoro-1H-pyrrole-2-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
