Description

Guanidinium p-Toluenesulfonate CAS NO 63144-77-4 is an organic salt formed from guanidine and p-toluenesulfonic acid. This compound is valued for its role as a versatile reagent and catalyst in organic synthesis, particularly in reactions requiring a strong, non-nucleophilic base or a source of the guanidinium cation. It is primarily sought by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for process development and scale-up.

Application

• Pharmaceutical Intermediate Synthesis: Used as a catalyst or reagent in the preparation of active pharmaceutical ingredients (APIs), particularly for heterocyclic compounds.
• Polymerization Catalyst: Acts as an efficient catalyst in polycondensation reactions for producing high-performance polymers and resins.
• Organic Synthesis Reagent: Employed as a strong, organic-soluble base in various condensation, alkylation, and deprotonation reactions.
• Agrochemical Manufacturing: Serves as a key building block or catalyst in the synthesis of certain herbicides, fungicides, and plant growth regulators.
• Biochemical Research: Utilized in studies involving protein denaturation or as a component in buffer systems for specific analytical techniques.
• Dye and Pigment Production: Functions as a catalyst or intermediate in the synthesis of complex organic colorants.

Quality Control

Our Guanidinium p-Toluenesulfonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) with lot-specific data are provided to guarantee traceability and consistency.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and handling properties.
