Meconin is a lactone of meconinic acid, extracted from opium. Meconin is a contaminating constituent from poppy that is present in heroin. Therefore, like Monoacetylmorphine - a metabolite of heroin, the presence of Meconin indicates the use of heroin and when found in umbilical cord tissue indicates fetal exposure to heroin. The use of meconin as a useful adjunct in detecting illicit opiate use is recommended.

Zinc iodide, Iodic acid (HIO3) zinc salt, is a chemical compound of zinc and iodine, ZnI2. It is an oxidative, white crystal or crystalline powder with molecular mass of 415.18534 g/mol. It is generally used as oxidant, analytical reagent and also used to manufacture electrical elements.

Zinc thiocyanate may be used in color printing. It is used in analytical chemistry, as a swelling agent for cellulose esters and dyeing assistant.

Nickel potassium cyanide is a nickel (II) salt, in which nickel cation is coordinated by four cyanide anions. Aqueous solution of nickel potassium cyanide has a characteristic orange-yellow color, and its formation is used for titration to determine contents of nickel.

N-(2-Acetamido)iminodiacetic Acid is a biological buffer component with sodium hydroxide and sodium chloride (pH 5.67-7.57, useful pH range 6.4-7.4). N-(2-Acetamido)iminodiacetic Acid is used to prepare immobilized pH gradients. ADA, or N-(2-Acetamido)iminodiacetic acid, can be used to study biological buffers and zwitterionic compounds. ADA has been used in a study to describe the application of scanning capacitively coupled contactless conductivity detection (SC(4)D) for the determination of pH dependant behaviour of two aminopolycarboxylates immobilised onto the surface of a monolithic capillary column. Blood cell stabilizing agent.

9β,10α,17α-pregna-4,6-diene-3,20-dione ((8S,9R,10S,13S,14S,17R)-17-Acetyl-10,13-dimethyl-8,9,10,11,12,13,14,15,16,17-decahydro-1H-cyclopenta[a]phenanthren-3(2H)-one) is an isomer of Dydrogesterone, a synthetic progestin largely used in hormone therapy, on the central nervous system by studying two markers of the neuroendocrine function. 9β,10α,17α-pregna-4,6-diene-3,20-dione is one of major impurities of dydrogesterone. The physiological and toxicological properties of this compound have not been evaluated in humans.

13-cis Retinol is one of the active metabolite of Vitamin A (all-trans Retinol). 13-cis Retinol is a retinoid inapplicable to the visual processes, and therefore it could be an important catabolic metabolite and its biosynthesis could be part of a process involved in regulating 11-cis-retinol concentrations within the retinal pigment epithelium of 11-cis-retinol dehydrogenase.

4-Hydroxy-4-(3-hydroxy-1-butenyl)-3,5,5-trimethyl-2-cyclohexen-1-one, (4R,3R)-(E)-(±)- is a terpenoid and one of vomifoliol isomers.

Silver Perchlorate is a light-sensitive mineral salt with the formula AgClO4. Silver perchlorate is created by heating a mixture of perchloric acid with silver nitrate. Alternatively, it can be prepared by the reaction between barium perchlorate and silver sulfate, or from the reaction of perchloric acid with silver oxide. Silver perchlorate is noteworthy for its solubility in aromatic solvents such as benzene and toluene. Silver Perchlorate is also amazingly soluble in water, up to 500 g per 100 mL of water. Similar to silver nitrate, silver perchlorate is an effective reagent for replacing halides ligands with perchlorate, which is a weakly or non-coordinating anion. The use of silver perchlorate in chemical synthesis has declined due to concerns about explosiveness of perchlorate salts.

Potassium tetracyanoplatinate is used in the preparation other salts like Krogmann's salt, that are highly conducting, one dimensional materials
