Description
Compared with other compounds in its class, the molecular weight of 552.62 g/mol gives Tetraethyl 1,1'-(1,4-phenylene)bis(2,5-dimethyl-1H-pyrrole-3,4-dicarboxylate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tetraethyl 1,1'-(1,4-phenylene)bis(2,5-dimethyl-1H-pyrrole-3,4-dicarboxylate) (CAS 83607-08-3), molecular formula C30H36N2O8 and molecular weight 552.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tetraethyl 1,1'-(1,4-phenylene)bis(2,5-dimethyl-1H-pyrrole-3,4-dicarboxylate) (C30H36N2O8) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.
CATO manufactures Tetraethyl 1,1'-(1,4-phenylene)bis(2,5-dimethyl-1H-pyrrole-3,4-dicarboxylate) 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.
