pyrogallol, also called pyrogallic acid, or 1,2,3-trihydroxybenzene, an organic compound belonging to the phenol family, used as a photographic film developer and in the preparation of other chemicals. Pyrogallol is an organic compound with the formula C₆H₃(OH)₃. It is a water-soluble, white solid although samples are typically brownish because of its sensitivity toward oxygen. It is one of three isomers of benzenetriols.

C6H6O3 -
Is pyrogallic acid an antiseptic?
Uses. One can find its uses in hair dyeing, dyeing of suturing materials and for oxygen absorption in gas analysis. It also has antiseptic properties. Pyrogallol was also used as a developing agent in black-and-white developers, but its use is largely historical except for special purpose applications. -
What is the function of pyrogallic acid?
pyrogallol, also called pyrogallic acid, or 1,2,3-trihydroxybenzene, an organic compound belonging to the phenol family, used as a photographic film developer and in the preparation of other chemicals. Pyrogallol was first obtained in 1786 from gallic acid, obtainable from galls and barks of various trees. -
Does pyrogallic acid absorb oxygen?
Literature pKa values: pyrogallol = 9.01 [75]; protocatechuic acid = 4.48, 8.83 [76]; 4-hydroxybenzoic acid = 4.58, 9.49 [77] The factors responsible for the potent antioxidant activity of gallic acid (GA) are explored by employing density functional theory (DFT). -
What chemical absorbs oxygen from the air?
Pyrogallic acid is the chemical which absorbs oxygen. This chemical is used to absorb the oxygen present in the conical flask in which seeds were kept for germination. In the absence of oxygen, the seeds fail to germinate. -
What is pyrogallic acid used for?
Pyrogallic acid is the chemical which absorbs oxygen. -
What chemical is used to remove carbon dioxide from the air?
Alkaline pyrogallic acid is used for absorbing during experiments on germination. (oxygen/carbon dioxide) -
What chemical absorbs oxygen from the air?
Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C6H4(OH)2. -
What removes CO2 from the atmosphere naturally?
Other strong bases such as soda lime, sodium hydroxide, potassium hydroxide, and lithium hydroxide are able to remove carbon dioxide by chemically reacting with it. In particular, lithium hydroxide was used aboard spacecraft, such as in the Apollo program, to remove carbon dioxide from the atmosphere. -
