Heterocyclic compounds are abundant in nature and are of great significance to life because their structural subunits exist in many natural products such as vitamins, hormones, and antibiotics [19, 20]; hence, they have attracted considerable attention in the design of biologically active molecules [21, 22] and advanced organic chemistry [23, 24].
Such compounds includes aliphatic hydrocarbons, aldehydes, alcohols, ketones, esters, carboxylic acids, some aromatic hydrocarbons (Figure 1), and oxygenated heterocyclic compounds such as lactones and alkylfurans (Mottram, 1998).
For example, Ribavirin (Figure 3) could be classified as 2934.99.9000 based on chemical classification, which provides for "Nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds: Other: Other: Other: Other: Other" and a disclaimer for this classification would state "Unless 'Drugs, then HTS - 2934.99.4700".
