5-Bromo-2,3,4,9-tetrahydro-1H-carbazol-1-one CAS 1100345-72-9

Description

The occurrence of 5-Bromo-2,3,4,9-tetrahydro-1H-carbazol-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-2,3,4,9-tetrahydro-1H-carbazol-1-one (CAS 1100345-72-9) is a high-purity analytical reference standard with the molecular formula C12H10BrNO and a molecular weight of 264.12 g/mol.

Structurally, 5-Bromo-2,3,4,9-tetrahydro-1H-carbazol-1-one (C12H10BrNO) 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 264.12 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).

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.

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.
