1,2-Propanediol 99% AR Grade Reagent
Cas Number:57-55-6
Formula:C3H8O2
Molar Mass:76.09
EC Number:200-338-0
Physicochemical properties：
Colorless viscous liquid with slightly spicy. It is easy to absorb moisture. It is stable under normal conditions and easy to form propionaldehyde, lactic acid, pyruvic acid and acetic acid at high temperatures. It is miscible with water, acetone and chloroform and soluble in ether. The relative density (d254) is 1.036. The freezing point is -59 ° C. The boiling point is 188.2 °C. The refractive index (n27D) is 1.4293. The flash point (open cup) is 99 ° C. Half lethal dose (rat, oral) 25 ml/kg.
Usage:
Solvent. Organic Synthesis. Antifreeze. Plasticizer. Fungicide. Gas chromatographic analysis standards. Gas chromatographic fixative (maximum use temperature 150 ° C, solvent chloroform), separation and analysis of alcohols, esters and ketones.
Packing:
500ml/25L/200L
