Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 238.12 g/mol gives 3-(2-Bromoethyl)-5-methyl-1H-indole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(2-Bromoethyl)-5-methyl-1H-indole (CAS 1260675-08-8), molecular formula C11H12BrN and molecular weight 238.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(2-Bromoethyl)-5-methyl-1H-indole (C11H12BrN) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
