Chemical Structure
Description
As a certified reference material (CRM), 3-Methyl-9H-carbazol-2-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-Methyl-9H-carbazol-2-ol (CAS 24224-30-4), molecular formula C13H11NO and molecular weight 197.23 g/mol, is a CATO reference standard with documented purity and traceability.
3-Methyl-9H-carbazol-2-ol (C13H11NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
