5-Isoquinolinesulfonyl chloride hydrochloride (1:1)(CAS: 105627-79-0)

5-Isoquinolinesulfonyl chloride hydrochloride is a white crystalline solid. It has a molecular weight of approximately 277.66 g/mol. This compound is sparingly soluble in water but soluble in common organic solvents. It is highly reactive, particularly under acidic conditions, and can undergo substitution reactions easily.

5-Isoquinolinesulfonyl chloride hydrochloride is typically synthesized by reacting isoquinoline with sulfonyl chloride in the presence of a suitable base such as pyridine. The reaction is often performed under anhydrous conditions to avoid hydrolysis, and the yield can be enhanced by using appropriate catalysts and optimizing reaction conditions.

5-Isoquinolinesulfonyl chloride hydrochloride is used in the pharmaceutical industry, where it serves as a building block for synthesizing various drugs. It is also utilized in the polymer industry for the modification of polymers and in the semiconductor industry for the production of organic semiconductors and thin films.

When handling 5-Isoquinolinesulfonyl chloride hydrochloride, it is essential to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. This compound should be handled in a well-ventilated area or under a fume hood due to its volatility and reactivity. Spills should be cleaned up immediately with appropriate absorbents, and the material safety data sheet (MSDS) should be consulted for detailed handling and disposal procedures.
