2-Pyrazinecarbaldehyde(CAS: 5780-66-5)

2-Pyrazinecarbaldehyde (CAS: 5780-66-5) is a crystalline solid with a molecular weight of approximately 123.11 g/mol. It is slightly soluble in water but more soluble in organic solvents like ethanol and acetone. Chemically, it is highly reactive, especially towards nucleophiles and reducing agents. It can undergo electrophilic aromatic substitution and condensation reactions.

2-Pyrazinecarbaldehyde (CAS: 5780-66-5) can be synthesized through the oxidation of pyrazine or by the condensation of a primary amine and a carboxylic acid. Common methods include using concentrated nitric acid or potassium permanganate as oxidants. The condensation method involves reacting an amine with formic acid in the presence of a catalyst such as p-toluenesulfonic acid.

2-Pyrazinecarbaldehyde (CAS: 5780-66-5) is primarily used in the pharmaceutical industry for the synthesis of drug intermediates. It is also utilized in the production of certain dyes and pigments, as well as in sensors for detecting various chemical and biological agents.

When handling 2-Pyrazinecarbaldehyde (CAS: 5780-66-5), it is crucial to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Ensure that the work is carried out in a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate absorbent materials and disposed of according to local regulations. Always consult the safety data sheet (SDS) for detailed handling and disposal information.
