Description

Allyl Chloroformate CAS NO 2937-50-0 is a highly reactive organic compound belonging to the chloroformate ester family, widely used as a versatile alkylating and protecting agent in advanced chemical synthesis. Its primary value lies in its ability to introduce the allyl group into target molecules, a crucial step in the production of pharmaceuticals, agrochemicals, and specialty polymers. This product is essential for R&D chemists and process engineers in the fine chemical, pharmaceutical intermediate, and polymer industries seeking efficient synthetic pathways.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for introducing the allyl protecting group in the multi-step synthesis of active pharmaceutical ingredients (APIs).
• Agrochemical Production: Used in the manufacture of herbicides, fungicides, and plant growth regulators as an alkylating agent.
• Polymer Chemistry: Serves as a monomer or cross-linking agent in the production of specialty resins and functional polymers.
• Peptide Synthesis: Employed as a carboxyl-protecting group (Alloc group) in solid-phase peptide synthesis (SPPS).
• Organic Synthesis Reagent: A fundamental building block for allylation reactions in laboratory-scale and industrial organic chemistry.
• Chemical Research & Development: Utilized in academic and industrial R&D for developing new synthetic methodologies and novel compounds.

Quality Control

Our Allyl Chloroformate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including Gas Chromatography (GC) and titration methods, to meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maintain stability and minimize decomposition. Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) when not in use. Keep away from strong acids, bases, and oxidizing agents.
