Description

2-Formylbenzenesulfonic Acid, Sodium Salt Hydrate is an important aromatic sulfonate derivative, serving as a versatile chemical intermediate and building block. Its value lies in the combined reactivity of the formyl (aldehyde) group and the sulfonate functionality, enabling its use in the synthesis of more complex molecules. This compound is primarily needed by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for research, development, and production processes.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a sulfonated aromatic core.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents where the benzenesulfonate moiety is critical for activity.
• Dye and Pigment Manufacturing: Serves as a precursor for sulfonated dyes and colorants, enhancing water solubility and fiber affinity.
• Specialty Surfactants: Acts as an intermediate in the creation of anionic surfactants with specific hydrophilic-lipophilic balance (HLB) properties.
• Chemical Research & Development: A valuable reagent for organic synthesis, including condensation reactions and as a precursor to heterocyclic compounds.
• Polymer Modification: Can be used to introduce sulfonate groups into polymer chains to alter solubility, ionic character, or other material properties.

Quality Control

Our 2-Formylbenzenesulfonic Acid, Sodium Salt Hydrate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and loss on drying is provided with every shipment to guarantee compliance with your project 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere to minimize oxidation.
