Description

Ritodrine CAS NO 26652-09-5 is a selective β2-adrenergic receptor agonist belonging to the tocolytic class of pharmaceuticals. It is primarily valued for its ability to relax uterine smooth muscle, making it a critical agent in specific obstetric protocols. This compound is essential for pharmaceutical manufacturers and research institutions focused on developing and producing medications for preterm labor management.

Application

• Pharmaceutical Active Ingredient (API): Primary use as the active component in injectable and oral formulations for tocolysis (inhibition of preterm labor).
• Reference Standard: Serves as a high-purity chemical standard for quality control and analytical method development in pharmaceutical laboratories.
• Biochemical Research: Used in pharmacological studies to investigate β2-adrenergic receptor signaling pathways and smooth muscle physiology.
• Formulation Development: Employed in R&D for creating new drug delivery systems, including controlled-release formulations.
• Metabolite Synthesis: Acts as a starting material or intermediate for the synthesis of ritodrine metabolites for pharmacokinetic studies.

Quality Control

Our Ritodrine is manufactured under strict quality management systems. Each batch is tested to meet high-purity standards suitable for pharmaceutical applications, with specifications typically aligned with pharmacopeial requirements. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to ensure traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption.
