An estimated 65% of all sodium chloride used in the United States goes toward industrial manufacturing, and another significant portion goes into medical solutions. This widespread use often leads to confusion, particularly over whether sodium chloride is the same as saline. The key distinction lies in chemistry: sodium chloride is the chemical compound, while saline is a solution created by dissolving sodium chloride in water.

Derived from the same root chemical, aspirin is technically a synthetic derivative of salicylic acid. To answer the question, **is aspirin and salicylic acid the same thing?** The simple answer is no—while related, they are distinct compounds with different chemical structures, uses, and side effects.

First synthesized in 1989 and approved by the FDA in 1996, mirtazapine is, in fact, a synthetic drug. Unlike medications derived from plants, its unique tetracyclic chemical structure is created entirely through a complex, multi-step process in a laboratory.

Activated charcoal, a powerful adsorbent, has been utilized for centuries to remove impurities from liquids and treat poisoning, showcasing the practical application of adsorption. In simple terms, adsorption is a process where molecules from a substance stick to the surface of another, a critical concept in medications and pharmacology.

Oxygen is the most abundant element by mass in the Earth's crust, but this essential component of our air has a complex identity. For those in healthcare and scientific fields, the question "does oxygen count as a substance?" leads to a nuanced answer that depends heavily on the context, particularly within the realms of chemistry and pharmacology.

First discovered in 1952 with erythromycin, macrolide antibiotics are a critical class of drugs used to treat a wide variety of bacterial infections [1.5.6, 1.3.4]. The answer to 'Why are they called macrolides?' lies in their distinct chemical structure.

Synthesized in 1846 by Ascanio Sobrero, nitroglycerine was immediately recognized as an extraordinarily unstable and dangerous liquid, so much so that its discoverer was terrified by his own creation. The same inherent chemical properties that made pure nitroglycerine so explosive also, paradoxically, paved the way for its eventual use in modern medicine.
