Used in the production of biodegradable plastics, particularly polyhydroxyalkanoates (PHAs), which are environmentally friendly alternatives to traditional petroleum-based plastics. It serves as a precursor in the synthesis of these polymers, which are utilized in packaging, agricultural films, and medical applications like sutures and drug delivery systems.

In the medical field, it is employed as a component in intravenous solutions for nutritional support, especially for patients with metabolic disorders or those requiring ketogenic diets. It helps in providing an energy source when glucose metabolism is impaired.

Additionally, it is used in research as a substrate for studying metabolic pathways, particularly those involving ketone bodies and energy metabolism. Its role in cellular energy production makes it a valuable tool in understanding conditions like diabetes, obesity, and neurodegenerative diseases.

In the cosmetic industry, it is incorporated into skincare products for its moisturizing and anti-aging properties, helping to improve skin elasticity and hydration.

It also finds applications in biotechnology for the development of microbial fermentation processes, where it acts as a carbon source for the production of various bio-based chemicals and materials.
