CAS 118-10-5 — Cinchonine

Cinchonine is an alkaloid derived from the bark of *Cinchona* trees, primarily used in pharmaceuticals as a chiral resolving agent and in research for its antimalarial properties, though it is less potent than quinine. It also serves as a precursor in organic synthesis and a standard in chiral chromatography. Cinchonine has the CAS number 118-10-5, carries no signal word under GHS classification, and appears as a white to yellowish crystalline powder with a bitter taste. It is soluble in ethanol and chloroform but poorly soluble in water. Molekula supplies Cinchonine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
