Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 264.16 g/mol gives 5'-Bromospiro[cyclohexane-1,3'-indole] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5'-Bromospiro[cyclohexane-1,3'-indole] (CAS 1375076-88-2) is a high-purity analytical reference standard with the molecular formula C13H14BrN and a molecular weight of 264.16 g/mol.
The molecular framework of 5'-Bromospiro[cyclohexane-1,3'-indole] (C13H14BrN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
