Valethamate bromide
Based on 1 Customer Validation
Valethamate bromide is an ester, serving as an effective rapidly acting anticholinergic antispasmodic and muscle relaxant. Valethamate bromide accelerates labor by improving cervical dilation. Valethamate bromide can significantly shorten the labor process and have fewer side effects.

Solvent & Solubility
DMSO : 100 mg/mL (258.82 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 50 mg/mL (129.41 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
