Chemical Structure
Description
4-chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine (CAS 307951-53-7), molecular formula C8H15ClN2 and molecular weight 174.67 g/mol, is a CATO reference standard with documented purity and traceability.
4-chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine (C8H15ClN2) 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-2-methyl-1H-pyrrolo[2,3-b]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.
