Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Iodo-2,3-dihydro-1H-indole hydrochloride (CAS 1187929-37-8) is a high-purity analytical reference standard with the molecular formula C8H8INHCl and a molecular weight of 281.52 g/mol.
The molecular framework of 4-Iodo-2,3-dihydro-1H-indole hydrochloride (C8H8INHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), 4-Iodo-2,3-dihydro-1H-indole hydrochloride 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.
