Description

3-Oxazolidinecarbonyl Chloride, 5-Methyl- (9Ci) is a versatile and highly reactive organic intermediate, specifically an acid chloride derivative of a substituted oxazolidine. Its core value proposition lies in its ability to efficiently introduce the 5-methyl-3-oxazolidinecarbonyl moiety into target molecules, serving as a crucial building block for the synthesis of more complex chemical architectures. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to create novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in the development of antibiotics, antivirals, and other bioactive molecules containing the oxazolidinone pharmacophore.
• Agrochemical Synthesis: Used in the production of advanced pesticides, herbicides, and fungicides, where its reactive carbonyl chloride group enables the creation of potent active ingredients.
• Peptide Mimetics & Prodrug Development: Employed to modify peptides or create prodrug forms, enhancing stability, bioavailability, or targeting specific biological pathways.
• Polymer Chemistry: Acts as a monomer or cross-linking agent in the synthesis of specialized polymers with unique properties for coatings or advanced materials.
• Chemical Research & Development: A critical reagent in organic synthesis laboratories for constructing heterocyclic compounds and exploring new chemical reactions.
• Ligand & Catalyst Preparation: Used to synthesize complex ligands for metal catalysts or organocatalysts used in asymmetric synthesis.

Quality Control

Our 3-Oxazolidinecarbonyl Chloride, 5-Methyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory needs.

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 (moisture-sensitive) nature and reactivity as an acid chloride, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition from moisture and air. Keep away from strong acids, bases, and oxidizing agents.
