Hydrochloride是什麼意思

"Hydrochloride" is a chemical compound suffix that indicates the presence of hydrochloric acid (HCl) as an ionic salt. It is formed when a base (often an amine) reacts with hydrochloric acid, resulting in a positively charged cation (usually an ammonium or metal ion) and a negatively charged chloride ion (Cl-). The resulting compound is called a hydrochloride salt.

For example, if a drug or chemical has a basic part (such as an amine group), it can be converted into its hydrochloride form to make it more stable or to adjust its solubility in water. This is a common practice in the pharmaceutical industry to improve the properties of drugs for easier formulation into tablets, capsules, or injectable solutions.

Hydrochloride salts are also commonly found in organic chemistry, where they are used as a way to stabilize or modify the reactivity of amines and other basic functional groups.
