Thionyl chloride is mainly used in the industrial production of organochlorine compounds, which are often intermediates in pharmaceuticals and agrichemicals.Mechanism of the Reaction of Alcohols with Thionyl Chloride First, a nucleophilic oxygen atom of the alcohol displaces a chloride ion from thionyl chloride to form a protonated alkyl chlorosulfite intermediate.

For use as a general nuclear stain for chromatin and mucin; for staining Nissl granules by end-point buffering and for showing malignant cells in frozen biopsy sections; and as a stain for semi-thin sections of plant material for light microscopy.

Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.

Thiosemicarbazone derivatives are of special importance because of their versatile biological and pharmacological activities. Thiosemicarbazides are potent intermediates for the synthesis of pharmaceutical and bioactive materials and thus, they are used extensively in the field of medicinal chemistry.

Thiazine red staining is a reliable and rapid pos-mortem diagnostic tool for Alzheimer´s disease.Derivatives of thiazine, often referred to as thiazines, are used for dyes, tranquilizers and insecticides.

Tetrachloroethylene is an excellent solvent for organic materials. Otherwise it is volatile, highly stable, and nonflammable. For these reasons, it is widely used in dry cleaning. It is also used to degrease metal parts in the automotive and other metalworking industries, usually as a mixture with other chlorocarbons.

TES BUFFER FOR BIOCHEMISTRY is solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.

It is used to prevent any change in the pH of a solution, regardless of solute. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. For example, blood in the human body is a buffer solution.

The thymidine analog 5-bromo-2′-deoxyuridine (BrdU) is used to label dividing cells. BrdU is injected intraperitoneally and incorporates into DNA being replicated where it will remain for the life of the cell.

Tetrabutyl ammonium iodide is used primarily when you need both a phase-transfer catalyst AND a co-catalyst to activate an alkyl chloride or bromide alkylating agent. An example is shown in the PTC Reaction of the month above.
