Silver oxide (Ag 2 O) was among the first reagents employed for this, [2] but a variety of other oxidising agents have been used successfully. [3] In solution, adrenochrome is pink and further oxidation of the compound causes it to polymerize into brown or black melanin compounds.
It is used as a non-nucleophilic base, being comparable to LiHMDS in terms of steric hindrance. Synthesis. It is synthesised by the deprotonation of 2,2,6,6- ...
Dyes. Active dyes are used to restore the body's natural colouration and counterstain against conditions such as jaundice as well as to indicate distribution of arterial fluid. Inactive dyes are used by the manufacturer of the arterial fluid to give a pleasant color to the fluid in the bottle but do nothing for the appearance of the embalmed body.

Sodium calcium edetate, an EDTA derivative, is used to bind metal ions in the practice of chelation therapy, such as for treating mercury and lead poisoning. [9] It is used in a similar manner to remove excess iron from the body. This therapy is used to treat the complication of repeated blood transfusions, as would be applied to treat ...
Samples used in the analyzers include, but are not limited to, blood, serum, plasma, urine, cerebrospinal fluid, and other fluids from within the body. [4] The design based on separating a continuously flowing stream with air bubbles largely reduced slow, clumsy, and error-prone manual methods of analysis.
It may be used to introduce the corresponding trifluoroacetyl group, for which it is more convenient than the corresponding acyl chloride, trifluoroacetyl chloride, which is a gas. It can be used to promote reactions of carboxylic acids, including Friedel-Crafts acylation and acylation of other unsaturated compounds.
Chelex resin is often used for DNA extraction in preparation for polymerase chain reaction by binding to cations including Mg 2+, which is an essential cofactor for DNases. Chelex protects the sample from DNases that might remain active after the boiling and could subsequently degrade the DNA, rendering it unsuitable for PCR.
