Properties and Applications of (2-CARBOXYETHYL)DIMETHYLSULFONIUM CHLORIDE

Physical and chemical properties

Dimethyl-β-propionic acid thiamethoxam is an aquatic attractant, similar to DMPT, vanillin, ethyl maltol (that is, fennel), betaine, etc. Among them, vanillin and ethyl maltol are widely used in fishing, and many baits and nests have them. Dimethyl-β-propionic acid thiamethoxam is mainly used for shellfish such as shrimps and crabs, and the effect of promoting the feeding of freshwater fish is not obvious. Some unscrupulous merchants edit DMPT into Baidu Encyclopedia through abnormal means to exaggerate the effect of DMPT, and even say that DMPT can be used for fishing. It is a complete trick.

Application

Dimethyl-β-propionic acid thiamethoxam is mainly used as a feed additive for aquaculture such as shrimps and crabs. It has a certain growth-promoting effect on shrimps and crabs, can promote the digestion of shrimps and crabs and the absorption of nutrients, and improve feed utilization. This feeding effect is a slow process, which requires long-term feeding to be able to be brought out, just like our long-term use of hawthorn can stimulate appetite and strengthen the spleen. It is worth noting that dimethyl-β-propionate is not suitable for fishing. This substance is only a feed additive. There is an essential difference between feed additives and fishing additives. The effect of feed additives is a long-term, slow process of promoting feeding, while fishing requires a quick and immediate feeding effect. All anglers who add DMPT to bait will not only not increase their catches, but will reduce them or even fail to catch any fish. This is because DMPT has an irritating smell that makes fish feel uncomfortable, and adding it to bait can easily lead to dead nests.
