Storage Stability:
In sealed original packing 12 months from production date, see remarks below*).
Storage Conditions:
Room temperature. We recommend maintaining the storage temperature between 20-40
 
°C (68-104 °F). Freezing and careful thawing cycles should not interfere with the quality
 
of the product.
 
Annotations:
Content and acid number are valid for the day of production.

 
*) 3-mercaptopropionic acid tends to oxidize at contact with air. This is the main reason for a slow decrease of content. The evolving water causes a slight increase of the acid number. Storage time is valid exclusively for originally sealed packages.
 
Standard Packaging:

Application:
 
3-Mercaptopropionic acid (3-MPA, MPA) and its derivatives are versatile compounds which are used as chain transfer and cross-linking agents in polymerizations, and as reactive intermediates in the production of PVC stabilizers. These compounds may also be useful as acidic ion exchange co-catalysts, coupling agents, and in UV-curable formulations.
