Chemical Structure
Description
6-Bromo-4-chloro-2,8-dimethylpyrido[2,3-d]pyrimidin-7(8H)-one (CAS 2641906-00-3) is a high-purity analytical reference standard with the molecular formula C9H7BrClN3O and a molecular weight of 288.53 g/mol.
Structurally, 6-Bromo-4-chloro-2,8-dimethylpyrido[2,3-d]pyrimidin-7(8H)-one (C9H7BrClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 288.53 g/mol, it falls into the medium-molecular-weight range. 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), 6-Bromo-4-chloro-2,8-dimethylpyrido[2,3-d]pyrimidin-7(8H)-one 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.
