Pyrazolo[1,5-a]pyridine(CAS: 274-56-6)

Pyrazolo[1,5-a]pyridine (CAS: 274-56-6) is a crystalline solid with a molecular weight of approximately 123.12 g/mol. It is slightly soluble in water and organic solvents like dimethylformamide (DMF) and acetonitrile. Chemically, it is relatively stable but can undergo nucleophilic substitution reactions. Its melting point is around 240°C, and it is commonly used in pharmaceutical and industrial applications.

Pyrazolo[1,5-a]pyridine (CAS: 274-56-6) is typically synthesized via the condensation of 1H-pyrazole and 2,6-dichloropyridine. Aqueous solutions of these precursors are heated to reflux in the presence of a base such as potassium carbonate. The reaction yields high selectivity and good yield, making it a common method in synthesis labs.

Pyrazolo[1,5-a]pyridine (CAS: 274-56-6) is widely used in the pharmaceutical industry for its potential as a drug candidate due to its biological activity. It is also utilized in the polymer industry for its potential as a monomer, in sensor technology for its sensing capabilities, and in the semiconductor industry for its electronic properties.

When handling Pyrazolo[1,5-a]pyridine (CAS: 274-56-6), it is important to wear appropriate personal protective equipment (PPE) such as gloves and eye protection. Work should be conducted in a fume hood to minimize inhalation risks. Spills should be cleaned up immediately following the manufacturer’s safety data sheet (SDS) guidelines. Ensure proper disposal and storage to avoid environmental contamination.
