Description

Bis-Linezolid CAS NO 908143-04-4 is a key pharmaceutical intermediate, specifically a dimeric derivative of the oxazolidinone antibiotic linezolid. This compound is of significant value in the synthesis and research of advanced antibacterial agents, offering a structural platform for developing novel therapeutics. It is primarily required by pharmaceutical manufacturers and research institutions engaged in the development of next-generation antibiotics and complex active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of novel oxazolidinone-class antibiotics and related compounds.
• Antibacterial Research: Used in medicinal chemistry research for structure-activity relationship (SAR) studies to develop new antibacterial agents with improved efficacy.
• API Development: Employed in the process development and scale-up manufacturing of complex active pharmaceutical ingredients.
• Reference Standard: Can be utilized as a reference standard or impurity marker in analytical method development and quality control for linezolid-based products.
• Chemical Synthesis: Acts as a specialized synthon in organic synthesis for constructing complex molecular architectures containing the oxazolidinone pharmacophore.

Quality Control

Our Bis-Linezolid is produced under strict quality management systems to ensure high purity and batch-to-batch consistency. The product undergoes rigorous analytical testing, including HPLC for assay and purity determination, to meet the stringent requirements of pharmaceutical R&D and manufacturing. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each batch to support your quality and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
