Description

Succinyl Chloride CAS NO 543-20-4 is a highly reactive diacid chloride primarily used as a key acylating and coupling agent in organic synthesis. Its bifunctional nature makes it an essential building block for creating linear polymers, pharmaceutical intermediates, and specialty chemicals. This compound is particularly valuable for industries focused on advanced material science, active pharmaceutical ingredient (API) development, and agrochemical manufacturing, where precise molecular construction is critical.

Application

• Pharmaceutical Intermediate: A key reagent in the synthesis of active pharmaceutical ingredients (APIs), particularly for creating succinate esters and amides.
• Polymer Chemistry: Serves as a monomer for the production of polyesters, polyamides (nylons), and other condensation polymers.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators requiring a succinyl moiety.
• Peptide Coupling Agent: Facilitates the formation of peptide bonds in laboratory-scale and industrial peptide synthesis.
• Organic Synthesis Reagent: Employed as a versatile acylating agent for introducing the succinyl group into alcohols, amines, and other nucleophiles.
• Dye and Pigment Manufacturing: Acts as an intermediate in the synthesis of certain dyes and organic pigments.
• Crosslinking Agent: Used in the production of crosslinked polymers and resins to modify material properties.
• Laboratory Research: A valuable tool for chemical research in academic and industrial R&D settings for novel compound creation.

Quality Control

Our Succinyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis by gas chromatography (GC), to ensure it meets precise specifications for reactivity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, alcohols, and water.
