| BPC (Bulk Pharmaceutical Chemical) | A pharmaceutical product derived by chemical synthesis, in bulk form, for later dispensing, formulation or compounding, and filling in a pharmaceutical finishing facility. Breakthrough Passage of a substance through a bed, filter, or process designed to eliminate it. For ion exchange processes, the first signs are leakage of ions (in mixed beds, usually Silica) and the resultant increase in conductivity. For organic removal beds, usually small, volatile compounds (Trihalomethanes (THMs) are common in activated carbon). |
