Chemical Structure
Description
The occurrence of 4,7-Dibromo-[1,2,5]thiadiazolo[3,4-c]pyridine is closely related to a nitrile group, sulfur-containing functionality, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,7-Dibromo-[1,2,5]thiadiazolo[3,4-c]pyridine (CAS 333432-27-2) is a high-purity analytical reference standard with the molecular formula C5HBr2N3S and a molecular weight of 294.95 g/mol.
The molecular framework of 4,7-Dibromo-[1,2,5]thiadiazolo[3,4-c]pyridine (C5HBr2N3S) is characterized by a nitrile group, sulfur-containing functionality, bromine substitution. 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.
As a certified reference material (CRM), 4,7-Dibromo-[1,2,5]thiadiazolo[3,4-c]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.
