Description

Sodium Alpha,4-Dihydroxy-3-Methoxytoluene-α-Sulphonate is a specialized organic sulfonate salt with significant utility as a versatile chemical intermediate. Its value lies in its unique molecular structure, which combines phenolic, methoxy, and sulfonate functionalities, making it a key building block for synthesizing more complex molecules. This compound is primarily needed by manufacturers in the pharmaceutical, agrochemical, and specialty dye industries for research and production processes.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a substituted phenolic core.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where its sulfonate group enhances solubility and bioavailability.
• Dye and Pigment Manufacturing: Acts as an intermediate for creating azo dyes and other complex colorants, contributing to color fastness and solubility properties.
• Research & Development: Employed in organic chemistry research for constructing novel molecular architectures and studying sulfonation reactions.
• Chemical Synthesis: Functions as a building block for surfactants, ligands, and other fine chemicals that benefit from its anionic and aromatic characteristics.

Quality Control

Our production of Sodium Alpha,4-Dihydroxy-3-Methoxytoluene-α-Sulphonate adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability. We employ advanced analytical techniques including HPLC, NMR, and IR spectroscopy for identity confirmation and purity verification. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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, which can affect product stability and handling properties.
