Chemical Structure
Description
3-(2-Chloroethyl)-1H-indole (CAS 32933-86-1) is a high-purity analytical reference standard with the molecular formula C20H18O8 and a molecular weight of 386.35 g/mol.
3-(2-Chloroethyl)-1H-indole (C20H18O8) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 3-(2-Chloroethyl)-1H-indole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
