Details

Phenol AS-LC is an organic reagent widely used in the field of chemical analysis. The following is an introduction to its nature, purpose, manufacturing method, and safety information:
nature:
Phenol AS-LC is a colorless to slightly yellow solid. It has good solubility and high solubility in alcohol, ether, and ketone solvents. It is a strong acidic dye that can form complexes with metal ions, resulting in bright color reactions.
Purpose:
Phenol AS-LC is mainly used for staining and quantitative analysis in analytical chemistry and biochemistry. It can be used to determine a large number of analytes, such as antioxidants (such as vitamin C) and polyphenolic compounds. Phenol AS-LC can also be used as an acid-base indicator, a selective dye for metal ions, and a reagent for photometric analysis.
Manufacturing method:
The preparation of phenol AS-LC generally adopts synthetic methods. One common preparation method is to react 2,2 '- bipyridinephthalein with o-hydroxybenzoic anhydride to synthesize the target product under acidic conditions.
Security information:
1. Phenol AS-LC may have irritating effects on the skin and eyes, and appropriate protective equipment should be worn during use.
2. Avoid inhaling or ingesting phenol AS-LC to prevent harm to the respiratory and digestive systems.
During the operation, it is necessary to maintain good ventilation conditions to reduce the accumulation of toxic gases.
