Pharmaceutical-grade Ropivacaine Hydrochloride (CAS 132112-35-7), 99–101%, supplied wholesale by Zyntex to licensed producers. Long-acting (S)-enantiomer local anesthetic API for epidural, nerve block and infusion products. CoA and SDS.
Ropivacaine hydrochloride monohydrate (C17H26N2O·HCl·H2O) is a white crystalline powder that is soluble in water. It is the pure (S)-enantiomer, so enantiomeric purity is a key specification.
Pharmaceutical companies use it in injection and infusion solutions for epidural anesthesia, nerve blocks and postoperative pain management. Compared with Bupivacaine Hydrochloride, it has a lower potential for cardiac and nervous system toxicity, and it is often preferred for continuous infusions. Other amide local anesthetics in our range include Lidocaine Hydrochloride and Prilocaine.
Because it is used in injections, sterile production with endotoxin control is required. Zyntex supplies it only to licensed pharmaceutical companies.
