Description
CATO manufactures Pyrazolo[1,5-a]pyridin-4-ol, 6-bromo-3-fluoro- under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Pyrazolo[1,5-a]pyridin-4-ol, 6-bromo-3-fluoro- (CAS 2770966-34-0), molecular formula C7H4BrFN2O and molecular weight 231.02 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, Pyrazolo[1,5-a]pyridin-4-ol, 6-bromo-3-fluoro- is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
