Process development equals process validation plus process optimization. A well-developed process is, therefore, by definition a well-validated process. Once it is decided that a bulk pharmaceutical chemical (BPC) process should be validated, the question becomes How In the case of a new process, the answer is simple Do a good process development job and document it (4). 

Process validation for a bulk pharmaceutical chemical (BPC) may include development data that describe the limitations and efficiency of the process. .. Their laboratory notebooks and their processing records also may be reviewed because these records may constitute the raw data for process validation (5). 

The focus of this chapter is bulk pharmaceutical chemical validation. Aside from the history section, the information presented to this point would apply to most any type of process. That commonality with other older validation efforts is deliberate. Bulk pharmaceutical chemical validation is unique, only to the extent that BPCs are unique. The underlying maxims of success for validation (the knowledge and understanding of the scientific basis upon which the equipment or process is based) are universal. Mastery of the overall approach equips one to effectively employ those concepts in a variety of settings. Some knowledge of the key concerns in the production of BPCs is essential to understanding how the validation of their preparation should be carried out. 

Bulk pharmaceutical chemicals resemble other types of products validated in the pharmaceutical industry in that they utilize various in-process controls to support and monitor the process through its execution. Typical controls that might be a part of a BPC process include material specifications. 

Profile This privately held company was founded in 1972. It is a full-service drug synthesis and chemical services company that performs a variety of laboratory, process scale-up, and manufacturing tasks including development of processes and synthesis routes for new medicinal products, validating bulk pharmaceutical processes, and authoring Drug Master Files. The company also has a pilot plant/small volume manufacturing site in North Andover, Massachusetts. 

In the preface to the first edition of this book pubiished in 2000, we said Industrial applications of homogeneous catalysis are proven, and a much wider application in the future is anticipated. Growth in the area of homogeneous catalysis with transition metal over the last 12 years has been phenomenal, and the innumerable number of patent applications and successful commercialization of selected processes in sectors as diverse as bulk chemicals, specialty polymers, and pharmaceutical intermediates have validated our anticipation.
