In the realm of industrial chemistry, understanding the precise properties of raw materials is fundamental to successful application and process optimization. 3-Nitrobenzyl Chloride (CAS 619-23-8) is a prime example of a versatile chemical intermediate whose utility is derived from its specific chemical characteristics. For procurement managers and chemical engineers, a thorough grasp of its physical and chemical properties, alongside its handling requirements, is essential for safe and efficient utilization. This guide provides insights into the key attributes of 3-Nitrobenzyl Chloride for industrial procurement.

3-Nitrobenzyl Chloride, with the chemical formula C7H6ClNO2 and a molecular weight of approximately 171.58 g/mol, is characterized by its chemical structure featuring a benzyl chloride group attached to a benzene ring substituted with a nitro group at the meta position. Typically, it appears as a white to pale yellow crystalline solid. Its melting point generally falls within the range of 41-46°C, meaning it can be handled as a solid at room temperature, simplifying storage and transportation. However, it's important to note that it has a relatively low flash point (around 110°C closed cup), indicating it is combustible and requires appropriate fire safety precautions.

The reactivity of 3-Nitrobenzyl Chloride is primarily attributed to the electrophilic nature of the benzyl carbon, readily undergoing nucleophilic substitution reactions. The nitro group, being an electron-withdrawing substituent, also influences the reactivity of the aromatic ring. These properties make it an excellent starting material for a wide range of organic synthesis reactions, including alkylations, esterifications, and reductions, commonly employed in the manufacturing of pharmaceuticals, dyes, and agrochemicals. When you buy 3-nitrobenzyl chloride online, paying attention to its purity, often specified at 98% or higher, is crucial for predictable reaction outcomes.
