Apexbio Technology LLC Arbutin 497-76-7 10g
Arbutin (CAS 497-76-7) is a naturally occurring glycosylated hydroquinone primarily isolated from bearberry (Arctostaphylos uva-ursi) leaves It acts as a competitive inhibitor of tyrosinase an enzyme central to melanin biosynthesis thereby modulating pigment production in biological systems Arbutin is extensively studied in cellular and biochemical assays investigating melanogenesis oxidative stress and potential antimelanogenic therapies Its ability to regulate melanin synthesis has made it a valuable research tool in dermatology cosmetic science and pharmacological studies focused on hyperpigmentation and related disorders The compound should be stored in a sealed cool and dry environment to maintain stability
