Overview
3-Hydroxypropionitrile is an organic compound with the molecular formula C3H5NO. It is a colorless to pale yellow liquid with a mild odor. This compound is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and specialty chemicals. Its reactivity and solubility in common solvents make it a versatile building block in organic chemistry. The production of 3-hydroxypropionitrile typically involves the reaction of acrylonitrile with water or other nucleophiles. It is commercially available in various purity grades, with higher purity grades being essential for pharmaceutical applications. The compound's stability and handling requirements are critical considerations for industrial users.
Physical and Chemical Properties
3-Hydroxypropionitrile is characterized by its high reactivity and hygroscopic nature. It has a density of 1.04 g/cm³ and a boiling point of 220-221°C. The compound is soluble in water, ethanol, and ether, which facilitates its use in various chemical reactions. Its melting point is relatively low at -50°C, making it a liquid at room temperature. One of the key properties of 3-hydroxypropionitrile is its ability to polymerize under certain conditions, such as exposure to heat or catalysts. This property necessitates careful storage and handling to prevent unwanted polymerization. The compound is also sensitive to moisture, which can affect its stability and performance in synthetic applications.
Main Applications
3-Hydroxypropionitrile is widely used as an intermediate in the pharmaceutical industry. It is a precursor for the synthesis of various drugs, including antihypertensive agents and antiviral medications. Its reactivity allows for the introduction of hydroxy and nitrile functional groups into more complex molecules. In the agrochemical sector, 3-hydroxypropionitrile is used to produce herbicides and pesticides. Its role as a building block in organic synthesis extends to the manufacture of specialty chemicals, such as dyes and fragrances. The compound's versatility and relatively low cost make it a valuable raw material for B2B buyers in these industries.
Safety and Storage
Due to its toxicity and irritant properties, 3-hydroxypropionitrile requires careful handling. Exposure can occur through inhalation, ingestion, or skin contact, leading to irritation or more severe health effects. Personal protective equipment (PPE), including gloves, goggles, and respirators, is essential when working with this compound. Storage conditions are critical to maintaining the stability of 3-hydroxypropionitrile. It should be kept in a cool, dry, well-ventilated area away from heat sources and open flames. Containers must be tightly sealed to prevent moisture ingress and polymerization. In case of spills, immediate containment and cleanup are necessary to minimize environmental and health risks.
B2B Procurement Guide
When procuring 3-hydroxypropionitrile, B2B buyers should prioritize supplier reliability and product quality. Key considerations include verifying the supplier's certifications, such as ISO or GMP, and confirming the compound's purity specifications. Bulk purchases often come with cost advantages, but storage capacity and shelf life must be evaluated. Packaging integrity is another critical factor, as improper packaging can lead to contamination or degradation. Buyers should also assess the supplier's logistics capabilities to ensure timely and safe delivery. Establishing long-term relationships with reputable suppliers can help secure consistent quality and competitive pricing.
