Description
As a certified reference material (CRM), 2-(3,4-DIchlorophenyl)-4h-furo[3,2-b]pyrrole-5-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-(3,4-DIchlorophenyl)-4h-furo[3,2-b]pyrrole-5-carboxylic acid (CAS 73014-94-5), molecular formula C13H7Cl2NO3 and molecular weight 296.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(3,4-DIchlorophenyl)-4h-furo[3,2-b]pyrrole-5-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
