Description

Guanidine-2-Cation CAS NO 25215-10-5 is a highly reactive organic cation, a protonated form of guanidine, which serves as a fundamental building block and intermediate in advanced organic synthesis. Its significance lies in its potent basicity and ability to form stable complexes, making it invaluable for constructing complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, particularly for developing active pharmaceutical ingredients (APIs) and high-performance materials.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing guanidine-based drugs, including antiviral agents, kinase inhibitors, and cardiovascular medications.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that require a guanidine functional group.
• Organic Synthesis Reagent: Employed as a strong, non-nucleophilic base and a precursor for creating guanidinium salts, ionic liquids, and supramolecular complexes.
• Bioconjugation & Protein Research: Useful in modifying peptides and proteins, and in studying enzyme mechanisms involving arginine residues.
• Material Science: Serves as a precursor for synthesizing nitrogen-rich polymers, resins, and flame-retardant additives.
• Analytical Chemistry: Can be used as a derivatization agent or a standard in chromatographic and spectroscopic analysis.

Quality Control

Our Guanidine-2-Cation is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and mass spectrometry, to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material must be stored in a cool, dry place under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Recommended long-term storage temperature is 2-8°C. The container should be kept tightly sealed when not in use.
