Description

Guanidine CAS NO 646-34-4 is a strong organic base with the chemical formula CH5N3. This versatile compound is a critical building block and reagent in organic synthesis and pharmaceutical manufacturing. It is essential for industries requiring high-purity intermediates, such as pharmaceuticals, agrochemicals, and specialty polymers. Its strong basicity and reactivity make it a valuable precursor for synthesizing a wide range of nitrogen-containing compounds.

Application

• Pharmaceutical Intermediate: A key starting material for synthesizing antiviral drugs (e.g., HIV protease inhibitors), antibiotics, and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators.
• Organic Synthesis Reagent: Employed as a strong base and nucleophile in various organic transformations, including the synthesis of heterocycles like triazines and pyrimidines.
• Polymer Industry: Serves as a catalyst or precursor in the manufacture of specialty polymers, resins, and flame retardants.
• Biochemical Research: Utilized as a protein denaturant in laboratory research and as a component in buffer solutions.
• Dye and Pigment Manufacturing: Acts as an intermediate in the synthesis of certain dyes and optical brighteners.

Quality Control

Our Guanidine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and industrial applications. We provide Certificates of Analysis (COA) with detailed specifications for purity, identity, and impurity profiles upon request, ensuring full traceability and compliance with your procurement requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of moisture and carbon dioxide from the air.
