Description

Lornoxicam Intermediate CAS NO 906522-88-1 is a key organic building block in the synthesis of the non-steroidal anti-inflammatory drug (NSAID) Lornoxicam. This high-purity intermediate is critical for ensuring the final API meets stringent pharmacopeial standards for purity and efficacy. It is primarily utilized by pharmaceutical manufacturers and advanced research facilities engaged in the development and production of analgesic and anti-inflammatory medications.

Application

• Primary Pharmaceutical Synthesis: As a crucial precursor in the multi-step synthesis of the active pharmaceutical ingredient (API) Lornoxicam.
• Research & Development: Used in medicinal chemistry research for developing novel COX-2 inhibitor analogs and studying structure-activity relationships (SAR).
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for the production of generic and branded Lornoxicam formulations.
• Analytical Reference Standard: Serves as a high-purity reference material for quality control and analytical method development in pharmaceutical labs.

Quality Control

Our Lornoxicam Intermediate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect stability and handling properties.
