“Other carboxylic acids with additional oxygen function”. This category of carboxylic acids includes organic compounds that contain both carboxyl (-COOH) and additional oxygen functional groups (-OH, -CHO, -CO-) in their chemical structure. These additional oxygen groups can be located on the same carbon atom as the carboxyl group or on a different carbon atom in the molecule.
Examples of carboxylic acids falling under this category include:
- Lactic acid: An organic acid that occurs naturally in dairy products and is produced by the human body during exercise.
- Tartaric acid: A white crystalline diprotic acid found in many fruits, especially grapes, and is used in the food industry as a flavoring agent and pH adjuster.
- Citric acid: A weak organic acid found in citrus fruits and used in the food industry as a flavoring agent, preservative, and pH adjuster.
- Gluconic acid: A carboxylic acid that is obtained by the oxidation of glucose and is used as a chelating agent in the food and pharmaceutical industries.
- Malonic acid: A dicarboxylic acid used in organic synthesis and in the manufacture of pharmaceuticals.
Some of the common examples of carboxylic acids that fall under this HSN code include:
- Glycolic acid (C2H4O3)
- Lactic acid (C3H6O3)
- Citric acid (C6H8O7)
- Tartaric acid (C4H6O6)
- Fumaric acid (C4H4O4)
These carboxylic acids find a wide range of applications in various industries including food, pharmaceutical, and chemical industries. They are used as flavoring agents, preservatives, pH adjusters, chelating agents, and in organic synthesis.
It is important to note that carboxylic acids with additional oxygen function are important building blocks in the production of a variety of chemicals, including plastics, detergents, and pharmaceuticals.
