Metol

Description:

Metol, also known as 4-methylaminophenol sulfate, is an organic compound primarily used as a developing agent in photographic processes. It appears as a white to light yellow crystalline powder and is soluble in water, which makes it effective in photographic developers. Metol is known for its ability to produce fine grain and high contrast in photographic images, making it a popular choice among photographers. The compound has a molecular formula of C7H9N2O3S and features both amine and phenolic functional groups, contributing to its reducing properties. In terms of safety, Metol can be harmful if ingested or inhaled, and it may cause skin and eye irritation, necessitating proper handling and protective measures during use. Additionally, it is important to store Metol in a cool, dry place away from incompatible substances to maintain its stability and effectiveness. Overall, Metol plays a significant role in traditional photographic chemistry, particularly in black-and-white film development.

4-Methylaminophenol sulfate

CAS: 55-55-0

4-Methylaminophenol sulfate is an enzyme substrate that is used in the analytical method for determining the concentration of potassium dichromate. It is prepared by reacting 4-methylaminophenol with sulfuric acid, and its optimum concentration is 0.2 mM. The linear calibration curve was obtained at a pH range of 2 to 5.4 and a temperature range of 25 to 37°C. The analytical method can be applied to human serum samples and has been shown to be applicable for studies on autoimmune diseases and anthelmintics.
