Wittig Reaction Reagent: This compound is a classic Wittig salt. When treated with a base, it forms a phosphorus ylide used to synthesize 2-vinylpyridine derivatives by reacting with aldehydes or ketones.
Pharmaceutical Synthesis: It serves as a vital intermediate in the synthesis of various biologically active molecules and drug candidates that incorporate a pyridine ring system.
Organic Building Block: Used in academic and industrial research for the construction of complex heterocyclic frameworks and π-conjugated systems.
Functional Materials: It can be employed in the development of specific ligands for coordination chemistry or as a precursor in the synthesis of specialized surfactants and dyes.

Standard Packaging: 25g, 100g, 500g per HDPE bottle or 25kg per fiber drum for commercial scale.
Customizable Packaging: Vacuum-sealed aluminum foil bags for moisture-sensitive requirements are available.
Shipping Precautions: Protect from moisture and air. The substance is sensitive to humidity. Standard chemical handling protocols apply.

Temperature: Store at Room Temperature (15-25°C). For long-term stability, storage at 2-8°C is often preferred by labs.
Protection: Hygroscopic. Keep container tightly sealed. Store under an inert atmosphere (e.g., Nitrogen) if possible to prevent moisture absorption.
Segregation: Keep away from strong oxidizing agents and strong bases (which could trigger ylide formation prematurely).
