Chemical Structure
Description
The occurrence of 2,2,4-trimethyl-1,2-dihydroquinoline hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,2,4-trimethyl-1,2-dihydroquinoline hydrochloride (CAS 34333-31-8), molecular formula C12H15NHCl and molecular weight 209.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,2,4-trimethyl-1,2-dihydroquinoline hydrochloride (C12H15NHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 2,2,4-trimethyl-1,2-dihydroquinoline 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.
