List of pharmaceutical compound number prefixes

This list of pharmaceutical compound number prefixes details a drug labeling standard. Pharmaceutical companies produce a large number of compounds, which cannot all be given names. Instead, they are systematically numbered for internal reference. The number is prefixed with a letter code indicating which company synthesized the compound. For example, CP-529414 is the compound number for the recently failed Pfizer experimental drug torcetrapib. If the company or its agents choose to publish information or research results about the drug before it has been assigned a generic name, they will refer to it by this number.
