2-Chloro-1-(1-ethyl-1H-indol-3-yl)ethanone CAS 38693-16-2

Description

Compared with other compounds in its class, the molecular weight of 221.68 g/mol gives 2-Chloro-1-(1-ethyl-1H-indol-3-yl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-1-(1-ethyl-1H-indol-3-yl)ethanone (CAS 38693-16-2), molecular formula C12H12ClNO and molecular weight 221.68 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, chlorine substitution, 2-Chloro-1-(1-ethyl-1H-indol-3-yl)ethanone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 221.68 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.
