2-Chlorothioxanthone, 98%

About 2-Chlorothioxanthone, 98%

2-Chlorothioxanthone is a monomer carrying the CAS registry number 86-39-5 at a purity of 98%. Formula C13H7ClOS, molecular weight 246.71 g/mol. The IUPAC name is 2-chlorothioxanthen-9-one. It is also known as 9H-Thioxanthen-9-one, 2-chloro- or 2-Chloro-9H-thioxanthen-9-one.

It is supplied as light yellow to yellow to green powder or crystals. Literature values give a melting point of 150-153 °C. Store in a tightly closed container in a cool, dry and well-ventilated place. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for polymerisation, crosslinking and curing and adhesives and coatings. Buyers come mainly from polymers and plastics and paints and coatings.

Standard pack sizes are 5 g, 25 g and 100 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
