Description

3-Methylpyridine-2-Sulfonic Acid Hydrate is a versatile heterocyclic sulfonic acid derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its dual functionality, combining the reactivity of a pyridine ring with the strong acidity and water solubility of a sulfonic acid group. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to create novel active ingredients and functional intermediates.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs targeting the central nervous system.
• Agrochemical Synthesis: Used in the development of modern pesticides, herbicides, and fungicides due to its bio-active heterocyclic structure.
• Ligand and Catalyst Preparation: Serves as a starting material for creating specialized ligands and organocatalysts used in asymmetric synthesis.
• Dye and Pigment Manufacturing: Functions as an intermediate in the production of complex organic dyes and colorants.
• Corrosion Inhibitor Formulation: Incorporated into specialty chemical formulations designed to protect metal surfaces in industrial applications.
• Research & Development: A valuable reagent for academic and industrial R&D in medicinal chemistry and material science.

Quality Control

Our 3-Methylpyridine-2-Sulfonic Acid Hydrate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, water content, and impurity profiles.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality and stability.
