Moderately toxic by intravenous route. When heated to decomposition it emits toxic vapors of SO_x.

Chondroitin sulfate (CAS NO.9007-28-7) is also named as Chondroitin polysulfate; Chondroitin sulfates; Chondroitin sulfuric acid; Chondroitin sulphate; Chonsurid; UNII-6IC1M3OG5Z; Chondroitin, hydrogen sulfate. Chondroitin sulfate is white or light yellow amorphous powder. It is soluble in water, insoluble in organic solvents. It is usually found attached to proteins as part of a proteoglycan.  Chondroitin sulfate as a health food or health care drugs is long used for control of coronary heart disease, angina, myocardial infarction, coronary atherosclerosis, myocardial ischemia and other diseases.
