Pantothenic acid is a water-soluble B vitamin composed of pantoic acid and β-alanine. It plays a crucial role as a structural component of coenzyme A (CoA), making it chemically significant in acyl transfer reactions and synthetic pathways. It is widely used in chemical, biochemical, and technical applications involving metabolic intermediates and coenzyme analogues.
Chemical and Physical Properties
Density: ~1.2 g/cm³ (estimated)
Melting Point: 190–192°C (decomposes)
Boiling Point: Not applicable (decomposes)
Solubility in Water: Freely soluble
Solubility in Other Solvents: Slightly soluble in ethanol; practically insoluble in ether and chloroform
Odor: Odorless
Applications
Organic Synthesis: Precursor or intermediate in the synthesis of CoA analogues and pantothenamides.
Biochemical Research: Used in studies of enzymatic acyl group transfers and metabolic regulation.
Chemical Manufacturing: Included in multi-component formulations requiring stable B-type carboxylic acids.
Coating and Polymer Science: Investigated as a component in water-soluble polymers and bio-based coatings.
Analytical Chemistry: Employed in the analysis of cofactor systems and amino acid derivatives.
