Chemical Structure
Description
2,7-Dibromodithieno[2,3-b:3',2'-d]pyridine (CAS 887573-13-9), molecular formula C9H3Br2NS2 and molecular weight 349.06 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution, 2,7-Dibromodithieno[2,3-b:3',2'-d]pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,7-Dibromodithieno[2,3-b:3',2'-d]pyridine 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.
