Chemical Structure
Description
The occurrence of 2-[(7-Bromo-2,1,3-benzothiadiazol-4-yl)methylene]malononitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-[(7-Bromo-2,1,3-benzothiadiazol-4-yl)methylene]malononitrile (CAS 1335150-10-1), molecular formula C10H3BrN4S and molecular weight 291.13 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-Bromo-2,1,3-benzothiadiazol-4-yl)methylene]malononitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-Bromo-2,1,3-benzothiadiazol-4-yl)methylene]malononitrile 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.
