Product Name:1,4-Butanediol bis(3-mercaptopropionate)
English Name:1,4-Butanediol bis(3-mercaptopropionate)
CAS No.:92140-97-1
Aliases:1,4-Butylene glycol bis(3-mercaptopropionate), Bis(3-mercaptopropionic acid) 1,4-butanediol ester
Molecular Formula:C10H18O4S2
Physical Properties:Colorless to pale yellow transparent liquid with a characteristic thiol odor. Molecular weight 266.38, relative density approximately 1.14 g/cm³ (25°C), boiling point approximately 192°C (0.4 mmHg), flash point >110°C. Insoluble in water, soluble in common organic solvents such as ethanol, acetone, and ethyl acetate. Contains two reactive mercaptan (-SH) functional groups with high reactivity; prone to oxidation in air, recommended storage under nitrogen in a sealed container.
Uses:Used as a reactive diluent and crosslinking agent in UV-curing systems, enhancing curing speed and crosslink density through thiol-ene click chemistry. Widely applied in coatings, inks, adhesives, photoresists, and other polymer material fields; also serves as a chain transfer agent for molecular weight control in polymer synthesis and resin modification.
Technical Specifications:
Content ≥95.0% (by gas chromatography)
Appearance: colorless to pale yellow transparent liquid
Boiling point: approximately 192°C (0.4 mmHg)
Relative density (25°C): 1.13-1.16
Flash point: >110°C, keep away from ignition sources
