Carprofen Specification
Carprofen , with CAS number of 53716-49-7, can be called (+/-)-6-chloro-alpha-methylcarbazole-2-acetic acid ; (+-)-9h-carbazole-2-aceticaci ; carprofeno;dl-6-chloro-alpha-methylcarbazole-2-aceticacid;imadyl . Carprofen (CAS NO.53716-49-7) is a non-steroidal anti-inflammatory drug that is used by veterinarians as a supportive treatment for the relief of arthritic symptoms in geriatric dogs. Carprofen can be used both short term, for joint pain or post-operative inflammation, or for day-to-day relief from the pain and inflammation associated with osteoarthritis, hip dysplasia, and other forms of joint deterioration .
