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 3-CHloro-pyrazolo[1,5-a]pyrimidin-7-ol.
3-CHloro-pyrazolo[1,5-a]pyrimidin-7-ol (CAS 2092930-03-3), molecular formula C6H4ClN3O and molecular weight 169.57 g/mol, is a CATO reference standard with documented purity and traceability.
3-CHloro-pyrazolo[1,5-a]pyrimidin-7-ol (C6H4ClN3O) contains an amide group, a hydroxyl group, an ether linkage, chlorine 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. 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.
CATO manufactures 3-CHloro-pyrazolo[1,5-a]pyrimidin-7-ol 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.
