Description

1,2-Diphenyl-3-Methyl-4-[Methylamino]-2-Butyl Propionate Maleate Salt is a specialized organic salt with significant utility in advanced chemical synthesis. This compound matters for its role as a key chiral intermediate or active pharmaceutical ingredient (API) precursor in the development of high-value, complex molecules. It is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries for process development and scale-up.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of novel therapeutic agents, particularly those targeting neurological or cardiovascular pathways.
• Chiral Catalyst or Ligand Precursor: Used in the development of asymmetric synthesis routes to produce enantiomerically pure compounds.
• Agrochemical Research: Acts as a precursor in the development of new generation pesticides or herbicides with specific modes of action.
• Fine Chemical Synthesis: Employed in custom synthesis and contract manufacturing for producing specialty chemicals with high purity requirements.
• Academic & R&D: Utilized in chemical research for studying reaction mechanisms, salt formation, and physicochemical properties of complex amines.
• Reference Standard: Can be supplied as a high-purity standard for analytical method development and quality control in regulatory submissions.

Quality Control

Our 1,2-Diphenyl-3-Methyl-4-[Methylamino]-2-Butyl Propionate Maleate Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chiral purity assessment, to ensure it meets the high standards required for pharmaceutical and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
