3 3′-Thiodipropionic Acid CAS 111-17-1

1. Acts 3 3′-Thiodipropionic acid as a key intermediate for synthesizing antioxidant esters (e.g., dilauryl thiodipropionate, DLTP) used in plastics and lubricants.
2. Serves 3 3′-Thiodipropionic acid CAS 111-17-1 as a crosslinking agent for polyurethane elastomers to enhance mechanical strength and chemical resistance of the products.
3. Functions as a chelating agent for metal ions in water treatment and a stabilizer for cosmetic formulations to prevent oxidation.

Store 3 3′-Thiodipropionic acid CAS 111-17-1 at 5–25℃ in sealed HDPE/amber glass drums in a cool, dry, well-ventilated area, away from light, strong oxidants and alkalis. Wear nitrile gloves and a dust mask; avoid inhalation of dust and prolonged skin contact (mild irritant). Reseal tightly post-use to prevent moisture absorption; dispose of waste via licensed chemical channels.

✅ Contains 3 3′-Thiodipropionic acid reactive carboxyl groups and a sulfur linkage, enabling efficient esterification and crosslinking reactions for polymer modification.
