Description

2H-Pyrido[3,2-B]-1,4-Oxazin-3(4H)-One,4-Ethyl-2-Fluoro-(9Ci) is a high-value, fluorinated heterocyclic compound that serves as a critical building block in advanced organic synthesis. Its unique fused pyrido-oxazine core with a fluorine substituent makes it a versatile intermediate for developing novel active pharmaceutical ingredients (APIs) and agrochemicals. This compound is primarily sought after by research institutions and industrial R&D departments in the pharmaceutical and agrochemical sectors for lead optimization and the creation of proprietary molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly for central nervous system (CNS) and anti-infective therapeutics.
• Agrochemical Research: Used as a core scaffold for developing new generation herbicides and fungicides with enhanced activity and selectivity.
• Chemical Biology Probe: Serves as a fluorinated tag or a heterocyclic core in the design of molecular probes for studying biological pathways.
• Material Science Research: Potential intermediate for synthesizing specialty chemicals and advanced organic materials with specific electronic properties.
• Contract Research & Manufacturing (CRAM): Supplied to CROs and CDMOs engaged in custom synthesis projects requiring complex fluorinated heterocycles.

Quality Control

Every batch of 2H-Pyrido[3,2-B]-1,4-Oxazin-3(4H)-One,4-Ethyl-2-Fluoro-(9Ci) is manufactured and tested under strict quality management systems. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for research and development. A detailed Certificate of Analysis (COA) including HPLC purity, identity confirmation (IR, NMR), and impurity profile is supplied with each shipment to guarantee traceability and batch-to-batch consistency.

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). Keep away from incompatible materials such as strong bases and fluorides. For long-term storage, consider inert atmosphere conditions to ensure optimal stability.
