Protheragen is a supplier of fine chemicals with a reputation for high purity, high performance specialty chemicals. Our strong R&D support, combined with our comprehensive quality control system allows us to provide our customers with a wide range of specialty intermediates, chiral building blocks, functional surfactants, and specialty synthetic reagents.

Core Fine Chemicals

• Pharmaceutical Intermediates & Chiral Building Blocks

Including chiral compounds such as (S)-(-)-1,2-Diaminopropane Dihydrochloride and highly reactive reagents like Aluminium Isopropoxide, provides critical raw materials for innovative drug R&D and synthesis.

• Surfactants & Emulsifiers

Comprising cationic (such as N-Hexadecyltrimethylammonium chloride), nonionic (Tween/Twain series, PEG series), and Monostearin, it has an excellent emulsifying, dispersing, and solubilizing effect.

• Functional Additives & Special Additives

Comprising stabilized additives (preservatives, thickeners); specialty esters as polymer modification monomers; and neutralizing/buffering agents (such as Triisopropanolamine).

• Organic Synthesis Building Blocks & Specialty Reagents

For example, Iodobenzene dicetate, which can be used for the synthesis of complex molecules and process development.
