Chemical Properties

Storage & Sensitivity
Ambient temperatures.
Insoluble in water.


Dowex® 50WX4 200-400 (H) is used to investigate the effect of particle size on drug loading and release profiles. Dowex® 50WX4 hydrogen form when treated in boiling water converted D,L-glyceraldehyde 3-phosphate diethyl acetal (barium salt) to free aldehyde D,L-glyceraldehyde 3-phosphate. It is a useful column packing material, used in anion exchange chromatography.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents.
