(5-Acetyl-1-methyl-1H-pyrrol-2-yl)methanesulfonic acid (CAS 794471-71-9), molecular formula C8H11NO4S and molecular weight 217.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5-Acetyl-1-methyl-1H-pyrrol-2-yl)methanesulfonic acid (C8H11NO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
