Introduction
Cocaine, a powerfully addictive stimulant, is derived from the leaves of the Erythroxylon coca bush, which is indigenous to South America (DEA, 2021). Although it is mostly known for its illegal use as a recreational drug, cocaine has a rich history of legitimate medical applications. This article aims to explore the chemical composition of synthesis cocaine, its synthesis process, and its legal and illegal uses.

Chemical Composition of Synthesis Cocaine
Cocaine, chemically known as benzoylmethylecgonine, is an alkaloid with the molecular formula C17H21NO4 (PubChem, 2021). It is a white, crystalline powder that dissolves in water or alcohol and has a bitter taste. Its chemical structure consists of a benzoyl group (COPh) attached to the methyl ester of the tropane alkaloid ecgonine. The presence of a double bond between the carbon atoms at the 1 and 2 positions in the tropane ring system distinguishes cocaine from other tropane alkaloids (El-Shazly et al., 2018).
Synthesis of Cocaine
The synthesis of cocaine from its precursor, ecgonine, involves a series of chemical reactions, including esterification and rearrangement reactions. The first step is the reaction of ecgonine with benzoyl chloride, a highly reactive compound, in the presence of a base, such as sodium hydroxide or potassium carbonate (Hajra et al., 2018). The result of this reaction is the formation of an intermediate compound, benzoylecgonine. The second step involves treatment of this intermediate with acid, resulting in a rearrangement of the benzoyl group from the carbonyl carbon to the nitrogen and generating the cocaine molecule.
Applications of Synthesis Cocaine
Medical Applications
Historically, cocaine has had legitimate medical uses as a local anesthetic and vasoconstrictor. Its anesthetic properties are attributed to its ability to block the sodium channels in the nerve membrane, preventing the transmission of nerve impulses. However, due to its high potential for abuse, it has been largely replaced by synthetic alternatives, such as lidocaine and prilocaine (Abrahão et al., 2015).
Illegal Applications
Cocaine is widely known for its illegal use for recreational purposes. It is usually snorted or smoked, and its effects include euphoria, increased alertness, and excitation. However, its use can lead to serious adverse health effects, such as cardiovascular and respiratory problems, seizures, and death (NIDA, 2021). Moreover, the illegal production and trafficking of cocaine result in significant societal costs, including violence, corruption, and environmental damage (UNODC, 2021).
Conclusion
Although synthesis cocaine has a rich history of legitimate medical use, its high potential for abuse has led to its replacement by synthetic alternatives. Nevertheless, the understanding of its chemical composition and synthesis process remains relevant for forensic, legal, and scientific purposes. It is crucial to continue studying the chemistry of synthesis cocaine to develop effective strategies for its detection, regulation, and prevention of its illegal use.
