Chloramphenicol is a broad-spectrum antibiotic that commonly appears in pharmaceutical form. It has low solubility in water, although it can dissolve to some extent. The solubility of chloramphenicol is influenced by factors such as temperature, pH, and water hardness.

Chloramphenicol is a compound composed of p-nitrophenyl, propylene glycol, and dichloroacetamide, and its antibacterial activity is closely related to the propylene glycol component. Its crystals appear white to pale yellow, forming fine needles or flakes, colorless, and have a strong bitter taste. Under dry conditions, its antimicrobial activity can remain stable for up to five years. When saturated with moisture, it can remain stable for several months when stored in a freezer or at room temperature under light. At room temperature, the solubility of chloramphenicol is approximately 25 mg/mL. However, its solubility increases in acidic environments; therefore, acidic substances such as acetic acid or hydrochloric acid are often added during the preparation of chloramphenicol solutions to enhance its solubility.

Chloramphenicol is a prescription medication and must be used under the guidance of a physician. It should be used exactly as directed by a doctor—do not adjust the dosage on your own, as this may lead to adverse reactions.
