L-Ascorbic Acid 6-stearate (Standard) is the standard substance of L-Ascorbic Acid 6-stearate, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. L-Ascorbic acid 6-stearate, a compound derived from L-ascorbic acid and stearic acid identified in K. coccinea, exhibits antioxidant and anticancer properties. It effectively scavenges DPPH radicals in cell-free assays (IC50 = 3.31 µg/ml). Additionally, lipid nanoparticles (LNPs) containing L-ascorbic acid 6-stearate have been shown to trigger apoptosis in HL-60 promyeloblasts at a concentration of 190 µM. This compound is also incorporated into cosmetic and personal care product formulations due to its beneficial effects.
