Biological activity:
MES (2 - Morpholinoethanesulphonic acid) is a kind of amphoteric ion buffer, the pH value of 5.5-7.7 range effectively. MES, as a Good's buffer, is widely used in plant culture media, reagent solutions, and physiological experiments to regulate pH.
Light yellow paste. The flash point was 149 ° C and the flow point was 60 ° C. The water solubility was 1% at 25 ° C. It has high detergency, excellent calcium soap dispersing power and hard water resistance. Good biological solubility.
Purpose:
This product is used as calcium soap dispersant in soaps and soaps. It can be used instead of sodium tripolyphosphate as low phosphorus or no phosphorus detergent. It can also be used as an active substance in liquid washing. It is used in industry as a medium foam mineral flotation agent. In leather degreasing, dyes, pigments, pesticides as dispersing agents, wetting agents. In the printing industry as a deinking agent.
It can be used as facial cleanser, shampoo type foam bath agent, tableware detergent, hand washing agent raw material, etc
"Biological buffer, used in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits."
Physical and chemical properties:
2-morpholine ethesulfonic acid is a white solid powder at room temperature and pressure, soluble in water, ethanol, methanol, acetone and other polar solvents, insoluble in non-polar solvents. Its molecular structure contains a morpholine ring and an ethosulfonate group. Morpholine ring is a nitrogenous heterocyclic compound, which is highly stable and inert, and has no obvious toxicity and irritation to organisms. The taurine group is a negatively charged functional group with good water solubility and buffering properties.
