Description
Compared with other compounds in its class, the molecular weight of 256.10 g/mol gives 1-(6-Bromo-5-hydroxyindolin-1-yl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(6-Bromo-5-hydroxyindolin-1-yl)ethanone (CAS 42443-15-2), molecular formula C10H10BrNO2 and molecular weight 256.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(6-Bromo-5-hydroxyindolin-1-yl)ethanone (C10H10BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 256.10 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
