CAS# 30374-01-7, EC# 250-157-6


Iso-Octyl 3-Mercaptopropionate, or IOMP, as well as other esters such as 2-Ethylhexyl 3-Mercaptopropionate 
(2-EHMP), CAS# 50448-95-8, 2-Ethylhexyl Thioglycolate 
(2-EHTG), CAS# 7659-86-1, and iso-Octyl Thioglycolate 
(-Mercaptoacetate) (IOTG), CAS# 25103-09-7, are used as raw materials in the manufacture of tin-based organic heatstabilizers for stabilizing PVC in the extrusion process to produce PVC products.

Iso-Octyl 3-Mercaptopropionate EC is produced with 3-Mercaptopropionic Acid from EVANS CHEMETICS as high purity distilled quality which is also suitable for export into countries with warm climate where a longer shelf life at elevated temperatures is required.

Iso-Octyl 3-Mercaptopropionate reacts like other mercaptanes and shows longterm stability.
