3-benzoyl-2-methyl-1H-indole CAS 26211-73-4

Description

Compared with other compounds in its class, the molecular weight of 235.28 g/mol gives 3-benzoyl-2-methyl-1H-indole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-benzoyl-2-methyl-1H-indole (CAS 26211-73-4), molecular formula C16H13NO and molecular weight 235.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-benzoyl-2-methyl-1H-indole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 235.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
