Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Methyl-5,7-dihydroindolo[2,3-b]carbazole (CAS 112485-52-6), molecular formula C19H14N2 and molecular weight 270.33 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H14N2, 6-Methyl-5,7-dihydroindolo[2,3-b]carbazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
