Chemical Structure
Description
3-Methyl-2,3-dihydro-1H-indole hydrochloride (CAS 21573-62-6) is a high-purity analytical reference standard with the molecular formula C9H11NHCl and a molecular weight of 169.65 g/mol.
The molecular framework of 3-Methyl-2,3-dihydro-1H-indole hydrochloride (C9H11NHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-Methyl-2,3-dihydro-1H-indole hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
