Description

Succinic Anhydride CAS NO 108-30-5 is a versatile cyclic dicarboxylic acid anhydride that serves as a critical building block in organic synthesis. Its high reactivity makes it an essential intermediate for creating a wide range of polymers, resins, and fine chemicals. This product is particularly valuable for manufacturers in the pharmaceutical, agrochemical, and polymer industries seeking reliable, high-purity raw materials for their production processes.

Application

• Polymer & Resin Production: A key monomer for synthesizing alkyd resins, unsaturated polyester resins (UPR), and polyimide precursors, contributing to coatings, adhesives, and composite materials.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs), including certain antibiotics, vitamins, and other therapeutic compounds.
• Agrochemical Synthesis: Serves as a precursor for manufacturing herbicides, fungicides, and plant growth regulators.
• Food & Flavor Industry: Employed in the production of food additives and flavoring agents, such as succinate esters.
• Surface Active Agents: Used to produce surfactants and detergents for industrial and consumer applications.
• Curing Agent for Epoxy Resins: Acts as a latent curing agent, providing controlled cross-linking and enhanced thermal properties in epoxy systems.
• Chemical Intermediate: A fundamental reagent for producing succinimide, succinamide, and other derivatives used across chemical sectors.
• Laboratory & Research: Utilized as a standard reagent in academic and industrial R&D for organic synthesis and material science.

Quality Control

Our Succinic Anhydride is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification. Certificates of Analysis (COA) documenting compliance with agreed specifications are provided with every shipment. We can support production under GMP guidelines for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to hydrolysis and reduced efficacy.
