Which of the following is NOT a component of finished product specifications?

Finished product specifications are critical for ensuring that a pharmaceutical product meets the necessary quality standards before it is released for distribution. These specifications typically include various aspects that directly relate to the product's quality, safety, and efficacy.

Physical appearances, such as color and shape, are essential elements of finished product specifications. These attributes help ensure that the product is visually consistent and meets the expected standards. Similarly, the concentration of the active ingredient is crucial because it determines the therapeutic effect and safety profile of the drug. Shelf life and storage conditions are also included in specifications, as they guide storage practices and inform about the stability of the product over time.

In contrast, sales projections are not related to the product's quality or safety. They pertain to the commercial aspect of the pharmaceutical business, indicating expected demand rather than defining what the product must be to meet regulatory standards. Therefore, sales projections do not fall under the component categories of finished product specifications, making this the correct answer.
