501821204
Ethyl Acetate 99.7% HPLC Grade Reagent
Cas Number:141-78-6
Formula:C4H8O2
Molar Mass:88.11
EC Number:205-500-4
Physicochemical properties:
Colorless transparent liquid. Fruity. volatile. Sensitive to the air. It can absorb water, which can slowly decompose and react acidicly. It is miscible with chloroform, ethanol, acetone and ether and soluble in water (10% ml/ml). It can dissolve certain metal salts (such as lithium chloride, cobalt chloride, zinc chloride, ferric chloride, etc.). The relative density (d204) is 0.902. The melting point is -83 ° C. The boiling point is 77 ° C. The refractive index (n20D) is 1.3719.
Usage:
The extractant that extracts many compounds (phosphorus, tungsten, arsenic, cobalt) from aqueous solutions. Organic solvents. It is used as a standard substance for calibration thermometers when separating sugars. Determination of bismuth, gold, iron, mercury, oxidants and platinum. Determination of bismuth, boron, gold, iron, molybdenum, platinum, potassium and cesium. Biochemical research, protein sequence analysis.
