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-chloro-1,3-dimethyl-1H-pyrazolo[4,3-c]pyridine.
4-chloro-1,3-dimethyl-1H-pyrazolo[4,3-c]pyridine (CAS 32487-67-5) is a high-purity analytical reference standard with the molecular formula C8H16ClN3 and a molecular weight of 189.69 g/mol.
4-chloro-1,3-dimethyl-1H-pyrazolo[4,3-c]pyridine (C8H16ClN3) contains a nitrile group, chlorine substitution. 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 4-chloro-1,3-dimethyl-1H-pyrazolo[4,3-c]pyridine 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.
