Quinine Hydrochloride Dihydrate TCI Q0030 is the hydrochloride salt of the cinchona alkaloid quinine, supplied as the dihydrate. The salt keeps the chiral framework of quinine and dissolves better in water and polar solvents than the free base. It belongs to the chiral catalysts, chiral ligands, and chiral reagents category. In the laboratory, it is used in asymmetric synthesis research and analytical studies. It is also a convenient source of quinine for preparing aqueous solutions.

Researchers choose the hydrochloride dihydrate form because its composition is well defined and it is easy to handle. Its fixed water content allows accurate stoichiometric calculations when preparing solutions of a specific concentration. Because it dissolves better in water, it works well in aqueous systems such as fluorescence measurements and biological assays. When a synthesis needs free quinine, the free base can be recovered by neutralization and extraction. The salt also keeps quinine's value as a resolving agent and as a starting material for chiral catalysts.

In Indonesia, quinine hydrochloride dihydrate serves analytical chemistry, pharmaceutical, and organic synthesis laboratories at universities and research institutions. Analytical groups use it to prepare aqueous quinine solutions. Synthesis groups working on asymmetric methods use it as a stable, well-characterized source of the cinchona scaffold. Its defined composition and practical handling make it a sensible stock reagent for teaching laboratories, graduate research projects, and institutional research programs across the country.

Store Quinine Hydrochloride Dihydrate in its original, tightly closed container in a cool, dry, well-ventilated place, away from direct sunlight and incompatible materials. Follow the storage conditions given on the TCI label and safety data sheet. A tightly sealed container helps keep the defined water content stable, which matters for accurate stoichiometry. When handling the material, wear gloves, safety glasses, and a laboratory coat. Weigh and transfer it in a way that keeps dust to a minimum, ideally under local exhaust ventilation. Avoid contact with skin and eyes, and do not breathe in the dust. Label all prepared solutions clearly, and dispose of waste according to institutional and local chemical waste rules.
