Chem-Supply Citric acid anhydrous AR

Citric acid anhydrous (C₆H₈O₇) AR grade is a high-purity, water-free crystalline organic acid supplied by Chem-Supply. AR (Analytical Reagent) grade confirms low impurity levels suitable for demanding analytical applications. The anhydrous form is preferred over the monohydrate where water content must be strictly controlled — particularly for primary standard preparation, precise stoichiometric calculations, and water-sensitive formulations.
