Description
CATO manufactures 3-Chloro-6,7,8,9-tetrahydro-5H-pyrido[2,3-b]indol-5-one 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.
3-Chloro-6,7,8,9-tetrahydro-5H-pyrido[2,3-b]indol-5-one (CAS 1005498-46-3), molecular formula C11H9ClN2O and molecular weight 220.65 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H9ClN2O, 3-Chloro-6,7,8,9-tetrahydro-5H-pyrido[2,3-b]indol-5-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
