Industrial, Electronic & Pharmaceutical Grade 1,3-Dimethyl-2-imidazolidinone (DMI) CAS 108-74-7 High Polar Aprotic Solvent for Organic Synthesis & Ele

1,3,5-Trimethylhexahydro-1,3,5-triazine (Abbr: MMA-Triazine / TMT, CAS:108-74-7,EINECS:203-612-8, HS Code:2933699090) is a colorless to pale yellow transparent liquid, a cyclic tertiary amine belonging to the hexahydrotriazine family. We supply industrial grade products with high purity complying with international quality standards. It features excellent H₂S and mercaptan scavenging performance, broad bactericidal activity, and good solubility in water and organic solvents. Widely used as desulfurization agent in oil & gas industry, biocide in water treatment, and intermediate in organic synthesis and polymer curing.

Applications
Oil & Gas Industry (Core Application)
High-efficiency non-regenerative H₂S and mercaptan scavenger for crude oil, natural gas and produced water treatment in sour oilfields. It rapidly reacts with hydrogen sulfide and alkyl mercaptans, reduces pipeline corrosion and equipment fouling, and generates no solid dithiazine byproducts that cause blockages, effectively improving production safety and extending equipment service life.
Water Treatment Industry
Broad-spectrum bactericidal agent for industrial circulating water, oilfield injection water and wastewater systems. It effectively inhibits sulfate-reducing bacteria, saprophytic bacteria and algae growth, controls microbial corrosion and biofilm formation, and maintains stable water quality in industrial circulation systems.
Organic Synthesis Intermediate
Key intermediate for synthesizing pharmaceutical ingredients, pesticide additives and fine chemical products. It serves as methylene amine source in organic reactions, and is also used to prepare cationic surfactants, corrosion inhibitors and other specialty chemicals.
Polymer & Coating Industry
Used as curing agent and crosslinking agent for epoxy resins, polyurethane and water-based coatings. It promotes crosslinking reaction, improves polymer thermal stability and mechanical strength, and enhances coating hardness and chemical resistance.
Metalworking Fluid Industry
Added to metal cutting fluids, grinding fluids and cooling liquids as preservative and bactericide. It inhibits microbial proliferation, extends working fluid service life, reduces workpiece corrosion, and improves processing stability and surface finish.
Leather & Paper Industry
Applied as preservative and fungicide for leather tanning and paper making processes. It prevents microbial degradation of raw materials, inhibits mildew growth, and improves product storage stability and service life.
