Chemical Structure
Description
As a certified reference material (CRM), 6-Bromo-4-fluoropyrazolo[1,5-a]pyridin-3-ol 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.
6-Bromo-4-fluoropyrazolo[1,5-a]pyridin-3-ol (CAS 2795141-86-3) is a high-purity analytical reference standard with the molecular formula C7H4BrFN2O and a molecular weight of 231.02 g/mol.
6-Bromo-4-fluoropyrazolo[1,5-a]pyridin-3-ol (C7H4BrFN2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
