Description

Palmitic acid, diester with 5-hydroxy-6-methylpyridine-3,4-dimethanol (CAS No. 31229-74-0), also known as Pyridoxine dipalmitate, is a high-purity ester derivative of pyridoxine (Vitamin B6) and palmitic acid. This lipophilic compound features the molecular formula C₄₀H₇₁NO₅ and a systematic IUPAC name of [4-(hexadecanoyloxymethyl)-5-hydroxy-6-methylpyridin-3-yl]methyl hexadecanoate. Ideal for lipid-based research, this compound is widely utilized in pharmaceutical, nutraceutical, and cosmetic applications due to its enhanced stability and bioavailability compared to free pyridoxine. Its unique structure enables improved solubility in non-polar matrices, making it a valuable ingredient in fat-soluble formulations. Available in >95% purity, this product is rigorously tested via HPLC, GC-MS, and NMR to ensure compliance with research-grade standards.

Application

Pyridoxine dipalmitate is primarily used as a stabilized, fat-soluble form of Vitamin B6 in lipid-based drug delivery systems and fortified foods. It serves as a key intermediate in synthesizing lipophilic prodrugs to enhance cellular uptake and bioavailability. Researchers also employ it in dermatological studies for its potential skin-conditioning and antioxidant properties. Additionally, it finds utility in nutraceutical encapsulation and as a reference standard in analytical chemistry.
