PYRIDINE (15N) - Introduction
Pyridine-15N (pyridine-15N) is a nitrogen isotope labeled pyridine compound. Its molecular formula is C5H5 ^ 15N, where 15N represents the isotope nitrogen -15 of the nitrogen atom. The following is a description of the properties, uses, preparation and safety information of pyridine-15N:
Nature:
Pyridine-15N is a colorless liquid with similar properties to ordinary pyridine. It has a density of about 1.04g/cm³, a boiling point of 114-116°C and a melting point of -42°C. It is soluble in many organic solvents such as ethanol, diethyl ether and dichloromethane.
Use:
Pyridine-15N is widely used in organic synthesis, pharmaceutical research, biochemistry and environmental analysis. Due to its stable isotope labeling properties, it can be used to trace drug metabolic pathways, study catalytic reaction mechanisms, and perform nuclear magnetic resonance (NMR) spectroscopy analysis.
Preparation Method:
Pyridine-15N can be prepared by chemical synthesis methods. One common method is to use a nitrogen -15 isotopically labeled nitrogen source, such as 15NH4Cl or the like, to react with an electrophile such as a bromoalkane to give pyridine-15N.
Safety Information:
Pyridine-15N is generally safe under normal conditions of use. However, as an organic solvent, pyridine-15N has certain toxicity and irritation, and direct contact with skin and eyes should be avoided. Appropriate protective measures, such as gloves and goggles, should be taken during use, and operation should be ensured in a well-ventilated environment. In case of accidental exposure or inhalation of pyridine-15N, wash off immediately and seek medical help. When disposing of waste, follow the appropriate chemical handling regulations.
