Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 316.15 g/mol gives 1-(4-bromobenzyl)-1H-indole-2,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(4-bromobenzyl)-1H-indole-2,3-dione (CAS 79183-37-2) is a high-purity analytical reference standard with the molecular formula C15H10BrNO2 and a molecular weight of 316.15 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 1-(4-bromobenzyl)-1H-indole-2,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
