Description

L-Pranoprofen is a high-purity, non-steroidal anti-inflammatory drug (NSAID) enantiomer, specifically the (S)-enantiomer of Pranoprofen. This compound is a critical chiral intermediate and active pharmaceutical ingredient (API) valued for its targeted pharmacological activity and reduced side-effect profile compared to racemic mixtures. It is essential for manufacturers in the pharmaceutical and fine chemical sectors developing advanced analgesic and anti-inflammatory medications. Our product, L-Pranoprofen CAS NO 103813-85-0, is supplied under stringent quality control to meet the exacting standards of global regulatory frameworks.

Application

• Pharmaceutical API Synthesis: Primary use as the active enantiomer in the manufacture of prescription-grade NSAID formulations.
• Chiral Intermediate: Serves as a key building block for the synthesis of more complex, enantiomerically pure therapeutic agents.
• Analgesic & Anti-inflammatory Drug Development: Core component in R&D for new drugs targeting pain, inflammation, and fever.
• Reference Standard: Used in analytical laboratories as a high-purity standard for quality control and method validation (HPLC, GC).
• Preclinical & Clinical Research: Employed in pharmacological studies to investigate the efficacy and safety of S-enantiomer specific therapies.
• Formulation Development: Utilized in creating various dosage forms such as tablets, capsules, and topical preparations.

Quality Control

Our L-Pranoprofen is manufactured and tested to meet the highest standards of purity and consistency required for pharmaceutical applications. Each batch undergoes comprehensive analytical testing, including chiral purity assay and impurity profiling via HPLC. We adhere to cGMP (current Good Manufacturing Practice) guidelines, and a comprehensive Certificate of Analysis (COA) detailing identity, purity, residual solvents, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Keep the container tightly sealed in a dry environment to prevent moisture absorption.
