Chemical Structure
Description
CATO supplies 5-Bromo-1-(2-chlorobenzyl)-1h-pyrazolo[3,4-b]pyridine (CAS 1016804-61-7), a certified reference material (molecular formula C13H9BrClN3, MW 322.59 g/mol) for analytical method development and quality control.
Structurally, 5-Bromo-1-(2-chlorobenzyl)-1h-pyrazolo[3,4-b]pyridine (C13H9BrClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 322.59 g/mol, it falls into the moderately-high-molecular-weight range. 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), 5-Bromo-1-(2-chlorobenzyl)-1h-pyrazolo[3,4-b]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.
