Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-bromo-7-fluoropyrazolo[1,5-a]pyridine.
4-bromo-7-fluoropyrazolo[1,5-a]pyridine (CAS 1427434-65-8), molecular formula C7H12BrFN2 and molecular weight 223.09 g/mol, is a CATO reference standard with documented purity and traceability.
4-bromo-7-fluoropyrazolo[1,5-a]pyridine (C7H12BrFN2) contains a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 4-bromo-7-fluoropyrazolo[1,5-a]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.
