Chemical Structure
Description
4-(4-Bromo-1h-pyrazol-1-yl)-3,5-difluorobenzaldehyde (CAS 1341477-93-7), molecular formula C10H5BrF2N2O and molecular weight 287.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(4-Bromo-1h-pyrazol-1-yl)-3,5-difluorobenzaldehyde (C10H5BrF2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 287.06 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), 4-(4-Bromo-1h-pyrazol-1-yl)-3,5-difluorobenzaldehyde 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.
