2-Chloro-4-hydrazinopyridine(CAS: 700811-29-6)

2-Chloro-4-hydrazinopyridine is a crystalline solid with a molecular weight of approximately 159.58 g/mol. It has a low solubility in water but is soluble in organic solvents such as ethanol and acetone. This compound is known to be reactive, particularly with nucleophiles, and can undergo substitution reactions. It is moderately stable but should be stored in a cool, dry place away from direct sunlight.

2-Chloro-4-hydrazinopyridine is typically synthesized via the reduction of 2-chloro-4-nitropyridine followed by an alkylation or amination step. Commonly, this involves the reduction of the nitro group to an amino group using sodium borohydride or similar reducing agents, followed by the introduction of the hydrazine moiety. The reaction conditions and catalysts used can vary depending on the desired yield and selectivity.

2-Chloro-4-hydrazinopyridine is primarily used in the pharmaceutical industry for the synthesis of certain drugs. It also finds applications in the polymer industry as a precursor for functionalized polymers. Additionally, it is explored for use in sensor technology and semiconductor manufacturing due to its reactivity and functional groups.

When handling 2-Chloro-4-hydrazinopyridine, appropriate personal protective equipment (PPE) should be worn, including gloves, goggles, and a lab coat. The compound should be handled in a well-ventilated area or a fume hood to minimize exposure to vapors. Spills should be addressed immediately using appropriate spill kits, and the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) should be referenced for specific spill procedures. Storage should be in a cool, dry place away from sources of heat and ignition.
