Tannic acid (TA) is a natural, non-toxic organic acid with corrosion inhibitive property for metals and alloys. A chemiluminescence (CL) system of KIO4 (potassium periodate)–H2O2 (hydrogen peroxide)–Tween40 has been employed in the detection of tannic acid in industrial wastewater. Tannic acid hydrolyzes to form mainly glucose and gallic acid. Its astringent property is due to the presence of polyphenolic groups.

Caution

At room temperature, concentrations over approximately 70% in water tend to form 1-2% thioglycolides per month, which hydrolyze to the original free compound when made acid or alkaline. The 70% solution oxidizes in air, but is stable at room temperature when tightly closed. Thioglycolate salts may also lose purity on storage. The exclusion of air does not materially improve stability.

Along with sodium borohydride, it forms an effective reagent for the reduction of:

carboxylic acid and acyl chloride to alcohols
carboxamides, oximes and lactams to amines
sulfoxides to sulfides

Titanium(IV) chloride (TiCl4) has been used as a precursor for the synthesis of Ag-TiO2@polyethylene glycol (PEG) nanoparticles. TiCl4 may also be used as one of the constituents to synthesize TiO2/Al2O3 binary oxide materials and N-(10-oxo-vinylanthracen-9-(10H)-ylidene)cyanamide.
Activates pyrrolidines for improved conversion, via a modified Bouveault reaction, to the corresponding ,-dimethylamines.

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

Novel metal oxide/phosphonate hybrids were formed from titanium(IV) isopropoxide in a two-step sol-gel process. Starting material for barium-strontium-titanate thin films. Used to make porous titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes. Applied in the formation of a heterosupermolecule consisting of a TiO2 nanocrystallite-viologen electron acceptor complex whose light-induced electron transfer has been demonstrated.
Commonly used as a precursor for the preparation of Titania (TiO2)
