Gallic acid (AR)

Gallic Acid, 25 – 100g
Product Profile
Gallic acid (3,4,5-trihydroxybenzoic acid) is a widely used phenolic compound and a primary reference standard in total phenolic content (TPC) determination. It is extensively applied in antioxidant studies, analytical chemistry, and phytochemical research due to its well-defined reactivity and stability.
