Product Description
2-(2-Hydroxyethyl)pyridine, with CAS No. 103-74-2, is a high-purity organic fine chemical, belonging to the pyridine derivative series and an important organic intermediate. It appears as a colorless to pale yellow or light orange transparent liquid, with a slight characteristic odor, uniform texture and no visible impurities or precipitates. This product has stable physical and chemical properties, good compatibility with most organic solvents such as ethanol and ether, soluble in water, and easy to absorb moisture. As a key pyridine derivative, it is widely used in organic synthesis, pharmaceutical research, agrochemicals and fine chemical fields, serving as a fundamental building block for organic synthesis, a metabolite of the anti-vertigo drug betahistine, and a raw material for preparing various pyridine-containing compounds, providing reliable support for industrial production, pharmaceutical R&D and scientific research activities.

1. Physical Properties
2-(2-Hydroxyethyl)pyridine is a colorless to pale yellow or light orange transparent liquid, with a slight characteristic odor, no sediment, suspended matter or mechanical impurities, and good fluidity. It has a density of 1.10 g/cm3 at 20℃, a boiling point of 139℃ (at 40 mmHg) and a flash point of 92℃, which is a combustible liquid and non-volatile under normal temperature and pressure. It is soluble in water, ethanol and ether, slightly soluble in chloroform and methanol, and has the property of being hygroscopic, easy to absorb moisture when exposed to air. Its melting point is around 38.49℃, and it has a refractive index of 1.54.
2. Chemical Properties
It is an organic pyridine derivative with stable chemical properties, not easy to oxidize or decompose under normal temperature and pressure, but should avoid contact with strong oxidants. It has amphoteric characteristics due to the presence of hydroxyl and pyridine groups, and can participate in various organic reactions such as substitution and addition reactions. It is relatively stable under weak acid and weak base conditions, and can be used as a proton donor in biochemical and physiological experiments, interacting with proteins, nucleic acids and enzymes. It meets the relevant quality standards of industrial-grade organic fine chemicals and organic intermediates.
3. Storage & Safety Properties
Storage: It should be stored in a dry, cool, well-ventilated and sealed environment, recommended to be stored below 15℃ in a dark place, and can be stored under inert gas if necessary. It should avoid moisture, high temperature, open flame, direct sunlight and contact with strong oxidants. It is not allowed to be mixed with toxic, harmful and corrosive substances, and the packaging should be kept intact to prevent moisture absorption, leakage, contamination and deterioration.
Safety: It is a combustible liquid (GHS07) and may cause skin irritation and serious eye irritation. Under normal operation, appropriate protective equipment (gloves, eye protection, face protection) should be worn, and it should be operated in a well-ventilated environment, with no smoking or open flame nearby. In case of accidental contact with skin, wash thoroughly with plenty of water; in case of eye contact, rinse cautiously with water for several minutes (remove contact lenses if present and easy to do) and continue rinsing. If skin or eye irritation persists, seek medical advice. This product is for industrial and scientific research use only, not for other purposes.
