Overview
Beta-Methylcholine Iodide is a quaternary ammonium compound widely used in biochemical and pharmacological research. It acts as a cholinergic agonist, specifically targeting muscarinic acetylcholine receptors. This compound is particularly valuable in studies exploring neurotransmission and receptor function. Its ability to mimic acetylcholine makes it a crucial tool for understanding cholinergic pathways. First synthesized in the early 20th century, Beta-Methylcholine Iodide has since become a standard reagent in neuroscience and pharmacology laboratories. Its stable crystalline form and solubility in water and alcohol facilitate its use in various experimental setups. Researchers often employ it to investigate the effects of cholinergic stimulation in both in vitro and in vivo models.
Physical and Chemical Properties
Beta-Methylcholine Iodide is characterized by its white crystalline appearance and molecular weight of 245.10 g/mol. It has a melting point of approximately 210°C, though it may decompose at higher temperatures. The compound is highly soluble in polar solvents such as water and alcohol, which makes it suitable for aqueous solutions used in laboratory experiments. As a quaternary ammonium salt, Beta-Methylcholine Iodide exhibits ionic properties, contributing to its stability and reactivity. Its molecular structure includes a positively charged nitrogen atom, which is essential for its interaction with cholinergic receptors. The iodide counterion enhances its solubility and bioavailability in biological systems.
Main Applications
The primary application of Beta-Methylcholine Iodide is in biochemical research, where it serves as a cholinergic agonist. It is commonly used to study the activation of muscarinic acetylcholine receptors, which play a critical role in the parasympathetic nervous system. Researchers utilize this compound to explore mechanisms of neurotransmission, receptor binding, and signal transduction. Beyond basic research, Beta-Methylcholine Iodide is also employed in pharmacological studies to evaluate the efficacy of anticholinergic drugs. Its ability to induce bronchoconstriction has made it useful in diagnostic tests for asthma and other respiratory conditions. However, such applications require strict medical supervision due to potential side effects.
Safety and Storage
Beta-Methylcholine Iodide should be handled with care to avoid exposure. Protective equipment, including gloves and goggles, is recommended when working with this compound. Inhalation or skin contact can lead to irritation, and ingestion should be avoided at all costs. Proper ventilation is essential to minimize airborne exposure. Storage conditions for Beta-Methylcholine Iodide include a cool, dry environment away from direct light. The compound should be kept in a tightly sealed container to prevent moisture absorption and degradation. Long-term stability is ensured when stored at room temperature, though refrigeration may extend shelf life for sensitive applications.
B2B Procurement Guide
When procuring Beta-Methylcholine Iodide, B2B buyers should prioritize suppliers who provide detailed product specifications, including purity levels and CAS number verification. Requesting a Material Safety Data Sheet (MSDS) is essential to ensure compliance with safety regulations. Bulk purchases may offer cost advantages, but buyers should confirm storage capabilities to maintain product integrity. Quality assurance is critical, especially for research applications where impurities can skew experimental results. Buyers are advised to seek suppliers with a proven track record in supplying high-purity biochemical reagents. Lead times and shipping conditions should also be considered to avoid delays or product degradation during transit.
