Dexpanthenol may be used as an analytical reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography techniques as well as partial least-squares multivariate calibration.

Dexpanthenol is an alcohol analog of pantothenic acid and an important component of parenterals, local cosmetic preparations and multi-vitamins. It has as much biological activity as pantothenic acid and is found to be stable in aqueous solution.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

DL-Panthenol is the alcohol analogue and biological precursor of DL-pantothenic acid. These analogues are precursors in the biosynthesis of coenzyme A. DL-Panthenol and D-Pantothenic acid are used in a variety of skin protection products. DL-pantothenic acid may have a role in controlling keratinocyte proliferation and differentiation. DL-Panthenol may be used for studies of skin protection emulsions from UV irradiation and as a humectant.
