Description

3,4-Dihydro-N,n-Dimethyl-1-(3-Methylphenyl)-3-Isoquinolineethanamine E Thanedioate (1:2) is a high-purity organic salt, specifically the ethanedioate (oxalate) salt of a substituted isoquinoline derivative. This compound is of significant value as a key pharmaceutical intermediate or reference standard in advanced research and development. It is primarily required by pharmaceutical companies, contract research organizations (CROs), and academic institutions engaged in the synthesis of novel therapeutic agents or detailed pharmacological studies.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the multi-step synthesis of potential drug candidates, particularly in central nervous system (CNS) research.
• Reference Standard: Used for analytical method development, validation, and quality control (QC) in pharmaceutical manufacturing and regulatory submissions.
• Biochemical Research: Employed in vitro and in vivo studies to investigate biological pathways, receptor binding affinity, and mechanism of action.
• Process Chemistry: Utilized for scaling up synthetic routes from laboratory to pilot plant and commercial production scales.
• Custom Synthesis: Acts as a starting material or precursor for the custom synthesis of more complex, target-specific molecules for clients.
