The HS code 29349990 refers to “OTHER HETEROCYCLIC COMPOUNDS”, which covers a wide range of organic compounds containing one or more heteroatoms (such as nitrogen, oxygen, or sulfur) in their ring structure. These compounds have various applications in the pharmaceutical, agrochemical, and fine chemical industries.
Some examples of compounds falling under this category include:
Pyridine derivatives:
Pyridine is a six-membered aromatic ring containing one nitrogen atom. It is a common building block in the synthesis of many drugs and agrochemicals.
Imidazole derivatives:
Imidazole is a five-membered aromatic ring containing two nitrogen atoms. It is found in many biologically active molecules, such as histamine and antifungal drugs.
Pyrimidine derivatives:
Pyrimidine is a six-membered ring containing two nitrogen atoms. It is a common structural motif in nucleic acids (DNA and RNA) and many drugs, such as antivirals and anticancer agents.
Triazole derivatives:
Triazole is a five-membered ring containing three nitrogen atoms. It is found in many drugs, such as antifungals and antivirals
Thiazole derivatives:
Thiazole is a five-membered ring containing both sulfur and nitrogen atoms. It is found in many biologically active molecules, such as vitamin B1 and antibiotics
The technical details of these compounds depend on their specific chemical structure and intended use. They can range from physical properties, such as melting and boiling points, to chemical properties, such as reactivity and stability.
