1-Naphthalenol,1-(dihydrogen phosphate) - Introduction
1-Naphthylphosphoric acid, also known as 1-naphthaleneacetic acid phosphate, is an organic phosphate compound.
Nature:
1-naphthoic acid is a colorless transparent solid, molecular formula is C12H11O3P, relative molecular mass is 246.19.
It has low vapor pressure and solubility, and can be dissolved in organic solvents such as ethanol and ether.
It will decompose at high temperatures and produce toxic phosphate gas.
Use:
1-naphthalene phosphoric acid has a wide range of applications in the field of chemistry. It is an organophosphatase inhibitor, which can be used to inhibit the activity of enzymes and study the catalytic mechanism of enzymes.
In addition, it is also used as a starting material for organic synthesis and can be used to prepare other compounds, such as active ingredients in medicines or pesticides.
Preparation Method:
1-naphthylphosphoric acid is generally obtained by reacting 1-naphthylacetic acid with an acid anhydride (e. g., acetic anhydride) in alcohol to give ethyl 1-naphthylphosphate. Next, the ethyl ester is converted to 1-naphthophosphoric acid by an acid hydrolysis reaction.
Safety Information:
1-naphthylphosphoric acid is an organic phosphorus compound with certain toxicity. Direct contact or inhalation of 1-naphthalene phosphate powder may cause harm to human body.
During use and operation, take necessary safety measures, such as wearing protective gloves, masks and goggles, and avoid direct inhalation of its powder or solution.
At the same time, it should be stored in a cool and dry place, away from fire and oxidants. If you take it by mistake or touch your skin, eyes, etc., you should seek medical attention immediately.
