Description
CATO manufactures Tetraethyl 1,1'-(ethane-1,2-diyl)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.
Tetraethyl 1,1'-(ethane-1,2-diyl)bis(2,5-dimethyl-1H-pyrrole-3,4-dicarboxylate) (CAS 131970-78-0) is a high-purity analytical reference standard with the molecular formula C26H36N2O8 and a molecular weight of 504.57 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Tetraethyl 1,1'-(ethane-1,2-diyl)bis(2,5-dimethyl-1H-pyrrole-3,4-dicarboxylate) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 504.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
