At NINGBO INNO PHARMCHEM CO., LTD., we understand that a deep knowledge of chemical compounds is essential for innovation and quality. Succinic acid, also known as butanedioic acid (CAS 110-15-6), is a fundamental organic chemical with a rich history and a broad spectrum of industrial applications. This dicarboxylic acid, with the molecular formula C4H6O4, serves as a crucial intermediate and functional ingredient across numerous sectors.

The production of succinic acid has evolved significantly. Traditionally, it was derived from the dry distillation of amber, hence its historical name 'amber acid.' Modern industrial production primarily involves two main routes: the hydrogenation of maleic anhydride, a petrochemical-based process, and increasingly, bio-based fermentation methods. These bio-fermentation processes utilize renewable feedstocks like glucose or other sugars, fermented by microorganisms such as *E. coli* or yeast, offering a more sustainable and environmentally friendly alternative. NINGBO INNO PHARMCHEM CO., LTD. stays abreast of these advancements to provide high-quality succinic acid sourced through reliable methods.

Physically, succinic acid typically presents as a white, crystalline powder or colorless crystals. It has a melting point of approximately 185-188°C and a boiling point of 236.15°C. It is moderately soluble in water and alcohols, but insoluble in less polar solvents. Chemically, as a dicarboxylic acid, it exhibits acidic properties and can participate in various reactions, including esterification, salt formation, and polymerization. These chemical properties are key to its utility as a building block in organic synthesis.

The industrial applications of succinic acid are extensive. It serves as a key precursor for the production of biodegradable polymers like polybutylene succinate (PBS), which are gaining prominence as eco-friendly alternatives to conventional plastics. In the pharmaceutical industry, it acts as an excipient, primarily for pH adjustment in formulations, and is also explored for its potential therapeutic benefits. Furthermore, it finds use in the manufacturing of resins, coatings, dyes, and photographic chemicals. Its role as a food additive (E363) for acidity regulation and flavor enhancement is also well-established.

Understanding the precise specifications, such as purity levels, moisture content, and melting point ranges, is crucial for industrial users. NINGBO INNO PHARMCHEM CO., LTD. ensures that its succinic acid products meet stringent quality standards required for these diverse applications. By providing access to well-characterized succinic acid, we aim to support the continuous innovation and development within the chemical, food, pharmaceutical, and material science industries.
