1. Aquatic Feed Attractant and Growth-Promoting Additive (Core Application) 🐟

• Activates the olfactory/gustatory receptors of fish, shrimp, and crabs, improving feeding rate and feed conversion ratio; suitable for freshwater and marine species such as carp, crucian carp, tilapia, yellow croaker, turbot, shrimp, and crabs.

• Also functions as a methyl donor, assisting in methionine synthesis and nitrogen metabolism, improving growth performance, survival rate, and stress resistance (tolerance to hypoxia and high temperature); often used in combination with betaine, amino acids, and vitamins.

2. Fishing Bait Additive (Consumer Application) 🎣

As a fish bait enhancer, it increases the speed of attracting fish and the duration of fish retention in the fishing area, especially suitable for conditions with low water temperature and low air pressure where fish have weak feeding intentions; small dosages are recommended to avoid repelling fish due to excessive concentration.

3. Osmotic Pressure Regulation and Stress Resistance in Aquaculture

Helps fish and shrimp maintain cellular osmotic pressure balance under stressful conditions such as sudden changes in salinity, water changes, and transportation, reducing stress damage and mortality; commonly used in seedling transportation, desalination/salinization acclimatization, and high-density aquaculture.

4. Animal Nutrition and Feed Functional Additive

Used in small quantities in poultry and livestock feed to assist in methyl metabolism and liver function protection, improving meat quality and feed utilization; dosage must be strictly controlled to avoid excessive accumulation and off-flavor residue.

5. Organic Synthesis and Pharmaceutical Intermediates 🧪

• As a sulfonium salt reagent, used as an intermediate in nucleophilic substitution, cyclization, oxidation, and other reactions; for example, in the preparation of sulfur-containing heterocyclic compounds, drug precursors, or functional material monomers.

• In pharmaceutical research and development, used to construct specific pharmacophores, or as a precursor for methylation reagents, suitable for the synthesis of small molecule drugs and biologically active molecules.

6. Analytical Chemistry and Standards

Used as a standard substance for ion-pair chromatography and mass spectrometry, for instrument calibration and quantitative analysis; can also be used as a probe molecule to study the reaction mechanism and biological metabolic pathways of sulfonium salts.
