Chemical Structure
Description
6,7-Diethoxy-1-methyl-1,2,3,4-tetrahydroisoquinoline HCl (CAS 336185-27-4), molecular formula C14H21NO2HCl and molecular weight 271.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6,7-Diethoxy-1-methyl-1,2,3,4-tetrahydroisoquinoline HCl (C14H21NO2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. 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.
As a certified reference material (CRM), 6,7-Diethoxy-1-methyl-1,2,3,4-tetrahydroisoquinoline HCl 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.
