> Applications
Gallic Acid is used by pharmaceutical, fine-chemical, nutraceutical-ingredient, cosmetic-ingredient, and research organizations developing phenolic-acid specifications, reagent methods, and downstream derivative programs. A 2016 Journal of Agricultural and Food Chemistry study reported UHPLC-MS/MS quantification of free and ester-bound gallic acid in foods and beverages, giving buyers analytical context for assay and sample-preparation planning (doi:10.1021/acs.jafc.5b04966). Ingredient supply is intended for qualified buyers who will confirm impurity strategy, local specification approach, labeling position, and finished-product obligations in their own markets.
Phenolic-acid analytical development
PubChem compound record CID 370 lists Gallic Acid as C7H6O5 with InChIKey LNTHITQWFMADLM-UHFFFAOYSA-N, providing identity context for analytical-development programs.
Intermediate and formulation development
Buyers typically evaluate assay by HPLC, related substances, residual solvents, loss on drying, residue on ignition, inorganic impurities where required, particle-size requirement, and packaging compatibility before moving from sample quantities to pilot or commercial batches. We supply bulk ingredient only, not finished consumer products, compounded preparations, or branded medicines.
