Chemical Structure
Description
The occurrence of Ethyl 3-bromo-1H-pyrazolo[3,4-c]pyridine-5-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 3-bromo-1H-pyrazolo[3,4-c]pyridine-5-carboxylate (CAS 2089291-71-2) is a high-purity analytical reference standard with the molecular formula C9H8BrN3O2 and a molecular weight of 270.08 g/mol.
Based on its molecular formula C9H8BrN3O2, Ethyl 3-bromo-1H-pyrazolo[3,4-c]pyridine-5-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Ethyl 3-bromo-1H-pyrazolo[3,4-c]pyridine-5-carboxylate 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.
