> Tannic Acid Ingredient — Overview
Tannic Acid (CAS: 1401-55-4, also known as gallotannic acid, tannicum acidum, and acide tannique) is a hydrolyzable tannin ingredient used in formulation, analytical-development, process-development, and intermediate programs where local regulations permit. Suzhou Pharmaceutical Technology Co., Ltd. supplies Tannic Acid Ingredient in controlled small-batch and bulk quantities from Suzhou, China, with export to South America, Australia, New Zealand, Mexico, Canada, and worldwide markets. Export documentation: COA and MSDS standard for all orders.

> Applications
Tannic Acid is used by pharmaceutical, fine-chemical, analytical, materials, and research organizations developing hydrolyzable-tannin specifications, complexation studies, protein-precipitation workflows, and downstream gallic-acid 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 context for hydrolyzable-tannin 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.
Hydrolyzable-tannin analytical development
PubChem compound record CID 16129778 lists Tannic Acid as C76H52O46 with InChIKey LRBQNJMCXXYXIU-PPKXGCFTSA-N, providing identity context for analytical-development programs. Because commercial tannic acid can represent a tannin mixture, buyers should align identity, assay, galloyl profile, and residual impurity expectations before order confirmation.
Process and intermediate development
Buyers typically evaluate assay by agreed method, related substances, free gallic acid profile, 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.
