4-(Ethoxycarbonyl)-5-formyl-3-methyl-1H-pyrrole-2-carboxylic acid (CAS 5448-14-6), molecular formula C20H6I4O5NaH2O and molecular weight 874.87 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(Ethoxycarbonyl)-5-formyl-3-methyl-1H-pyrrole-2-carboxylic acid (C20H6I4O5NaH2O) is characterized by a salt form, a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 4-(Ethoxycarbonyl)-5-formyl-3-methyl-1H-pyrrole-2-carboxylic acid 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.
