Description

3-(2-Chloroethyl)-2-Methyl-6,7,8,9-Tetrahydro-4H-Pyrido[1,2-A]Pyrimidin-4-One n-Oxide is a high-purity, advanced pharmaceutical intermediate with significant synthetic utility. This compound matters for its role as a key building block in the development of novel active pharmaceutical ingredients (APIs), particularly within the central nervous system (CNS) and other therapeutic areas. It is primarily needed by research institutions, pharmaceutical R&D departments, and fine chemical manufacturers engaged in process development and scale-up for new drug candidates.

Application

• Pharmaceutical Intermediate: Critical building block for the synthesis of novel drug candidates, particularly in neurological and psychiatric research.
• Organic Synthesis Research: Used in academic and industrial laboratories for constructing complex heterocyclic frameworks and studying structure-activity relationships (SAR).
• Process Chemistry Development: Serves as a key starting material (KSM) or advanced intermediate in the optimization and scale-up of API manufacturing routes.
• Reference Standard: High-purity material for analytical method development, validation, and quality control in pharmaceutical production.
• Biochemical Research: Potential tool compound for probing biological pathways and enzyme interactions in early-stage discovery.

Quality Control

Our 3-(2-Chloroethyl)-2-Methyl-6,7,8,9-Tetrahydro-4H-Pyrido[1,2-A]Pyrimidin-4-One n-Oxide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical R&D. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each 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 (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric humidity.
