Barium tetracyanoplatine is a fluorescent substance that emits light when it is excited by photons. A screen employing barium tetracyanoplatine was the first radiation detector and made possible the discovery of X-rays by Röntgen.

There is no information related to biological or pharmacological application of lead(II) thiocyanate. It is only known, that this substance is a water soluble and can lead to the skin irritation and lead poisoning by ingestion or inhalation.

Silver nitrite is an mineral salt with the formula AgNO2. Silver nitrite is produced from the reaction between silver nitrate and an alkali nitrite, such as sodium nitrite. Silver nitrite is much less soluble in water than silver nitrate, and a solution of silver nitrate will readily precipitate silver nitrite upon addition of sodium nitrite. Silver nitrite is used in the silver plating process, hair dye, inks, permanent marker pens and determination of chloride ions in water and drilling fluids. It is used as Tollen's reagent and used in the formation of aniline and nitro compounds in victor mayer reactions.

Zinc perchlorate is an antifungal agent. It was also found to be a highly efficient catalyst for acylation of electron deficient phenols, sterically hindered alcohols and electron deficient and sterically hindered amines.

Copper butyrate is a member of the homologous series, the copper alkanoates. It forms dark green color crystals. It is used in organic synthesis as the catalyst and used in lubricants.

THIOCTIC ACID, (-)- is less biologically potent enantiomer of thioctic acid than (+)-enantiomer. Dihydrolipoamide dehydrogenase from human renal carcinoma does not accept the S-enantiomer as a substrate in comparison to R-enantiomer but S-enantiomer is an inhibitor of the overall reaction of the bovine pyruvate dehydrogenase complex. Chronic parenteral treatment with the antioxidant alpha-lipoic acid enhances insulin-stimulated glucose transport and non-oxidative and oxidative glucose metabolism in insulin-resistant rat skeletal muscle, with the R-(+) enantiomer being much more effective than the S-(-) enantiomer. The racemate of lipoic acid at high dosage reduced the life span significantly of immunosuppressed mice but the S(-)-enantiomer of lipoic acid increased the 50% survival rate. The thioctic acid, (-)- was shown to be toxic when administered to thiamine-deficient rats.

Ellman's reagent 5,5'-dithio-bis-(2-nitrobenzoic acid), also known as DTNB, was introduced in 1959 as a versatile water-soluble compound for quantitating free sulfhydryl groups in solution. In this procedure, DTNB, a symmetric aryl disulfide, reacts with the free thiol to give a mixed disulfide plus 2-nitro-5-thiobenzoic acid (TNB) which is quantified by its absorbance at 412 nm. Determination of SH groups in proteins by Ellman's reagent after or in the presence of NO treatment is complicated since the reduced form of DTNB, TNB, can be reoxidized by NO back to DTNB, with subsequent loss of absorbance at 412 nm.

Cobaltous cyanide is a catalyst for organic synthesis.

There is no information about biological or pharmacological application of lead hexafluorosilicate, this substance is used for research in chemistry.

There is no information about biological or pharmacological application of Nickel(II) acetylacetonate. But is known, that this substance is the precursor to nickel-based catalysts.
