Description

Ciramadol is a synthetic opioid analgesic compound with significant research and pharmaceutical development interest. Its primary value lies in its potent analgesic properties, which have been studied for the management of moderate to severe pain. This compound is of particular relevance to pharmaceutical research and development laboratories, active pharmaceutical ingredient (API) manufacturers, and organizations involved in preclinical and clinical studies of central nervous system (CNS) agents.

Application

• Pharmaceutical Research & Development: As a key intermediate or reference standard in the development of novel analgesic drugs and CNS-targeting therapies.
• Active Pharmaceutical Ingredient (API) Manufacturing: For use in the synthesis of finished dosage forms under controlled, GMP-compliant processes.
• Preclinical & Clinical Studies: Serving as a critical compound for pharmacological profiling, efficacy testing, and safety assessment in animal models and human trials.
• Analytical Reference Standard: Used in quality control laboratories for method development, validation, and routine assay testing via HPLC, GC, or spectroscopy.
• Biochemical Research: Investigation of opioid receptor binding affinity, mechanism of action studies, and structure-activity relationship (SAR) analysis.
• Controlled Substance Analog Research: For authorized research into the properties and effects of synthetic opioids within regulatory frameworks.

Quality Control

Our Ciramadol is manufactured and handled under strict quality management systems to ensure batch-to-batch consistency and purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to meet the stringent requirements of pharmaceutical research and development. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your regulatory and quality documentation needs.

Storage

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