What is the primary use of Isopropyl Alcohol 70% (IPA) in a pharmacy setting?

The primary use of Isopropyl Alcohol at a concentration of 70% in a pharmacy setting is for disinfecting and cleaning various areas. This concentration is particularly effective as a disinfectant because it strikes an ideal balance; it is strong enough to denature the proteins of microorganisms, leading to their destruction while also allowing for sufficient penetration into their cell membranes. Disinfecting surfaces, tools, and equipment in pharmacies is crucial for maintaining a sterile environment and preventing cross-contamination, thus ensuring patient safety and the integrity of medications.

While it is also used in cleaning laboratory instruments, the broader application of disinfecting and cleaning various areas captures its full utility in pharmacy practices, making it the more appropriate answer. The other options refer to specific uses that do not encompass the primary and broad application of Isopropyl Alcohol in a pharmacy.
