Chemical Structure
Description
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.
33107-73-2 1-(6-chloro-9-methyl-9H-carbazol-3-yl)ethanone DTXSID80385726 (CAS 33107-73-2), molecular formula C15H12ClNO and molecular weight 257.71 g/mol, is a CATO reference standard with documented purity and traceability.
33107-73-2 1-(6-chloro-9-methyl-9H-carbazol-3-yl)ethanone DTXSID80385726 (C15H12ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
