The trade name Red-Al refers to its being a reducing aluminium compound. It is used predominantly as a reducing agent in organic synthesis. The compound features a tetrahedral aluminium center attached to two hydride and two alkoxide groups, the latter derived from 2-methoxyethanol. Commercial solutions are colorless/pale yellow and viscous.
Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...

The first patent for an oxygen scavenger used an alkaline solution of pyrogallic acid in an air-tight vessel. [7] [8] Modern scavenger sachets use a mixture of iron powder and sodium chloride. [8] Often activated carbon is also included as it adsorbs some other gases and many organic molecules, further preserving products and removing odors.
Memory erasure has been shown to be possible in some experimental conditions; some of the techniques currently being investigated are: drug-induced amnesia, selective memory suppression, destruction of neurons, interruption of memory, reconsolidation, [1] and the disruption of specific molecular mechanisms.
Pararosaniline, pararosaniline free base, Basic Red 9, or C.I. 42500 is an organic compound with the formula (H 2 NC 6 H 4) 2 C=(C 6 H 4 NH). [1] It is the free base form of pararosaniline hydrochloride , [(H 2 NC 6 H 4 ) 3 C] + Cl − , a magenta solid with a variety of uses as a dye .
Cresyl violet is used to stain Heinz bodies in red blood corpuscles or for staining of the neurons in the brain and spinal cord. It is used to demonstrate the Nissl substance in the neurons and cell nuclei. In this role it is also often used as a counterstain to Luxol fast blue, which stains the myelin.
The solution takes the name from British chemist Henry Drysdale Dakin (1880–1952) who developed it in 1916, during World War I, while he was stationed at a field hospital in Compiègne. He worked there in collaboration with French physician Alexis Carrel , and the particular use they made of the solution is known as the Carrel–Dakin method ...
