For R&D scientists and product formulators, a deep understanding of a chemical intermediate's properties and synthesis is fundamental to innovation and successful product development. 4-Chlorobenzaldehyde (CAS 104-88-1) is a prime example of a chemical that, with its well-defined properties and accessible synthesis routes, empowers advancements across multiple scientific disciplines. As a committed supplier of fine chemicals, we aim to provide clarity on this crucial compound.

Understanding the Core Properties: 4-Chlorobenzaldehyde is typically described as a white to pale yellow crystalline solid or powder. Its chemical structure features a benzene ring substituted with a chlorine atom at the para position and an aldehyde group. This combination makes it reactive and suitable for a wide range of chemical transformations. Key physical properties include a melting point typically in the range of 46-48°C and a boiling point around 213-214°C. Its solubility in water is limited (around 935 mg/L at 20°C), but it readily dissolves in common organic solvents such as ethanol, ether, and benzene. The compound is noted to be air-sensitive, requiring appropriate storage conditions to maintain its integrity. These properties are vital for chemists when planning reactions and handling the material.

Synthesis Pathways for 4-Chlorobenzaldehyde: Several methods exist for the synthesis of 4-Chlorobenzaldehyde, making it a readily available intermediate. A common industrial route involves the chlorination of p-chlorotoluene. This process often starts with the reaction of p-chlorotoluene with phosphorus trichloride, followed by controlled chlorination under light. Alternatively, oxidation of p-chlorotoluene or p-chlorobenzyl alcohol can also yield 4-Chlorobenzaldehyde. For researchers and industrial chemists looking to buy or synthesize this compound, understanding these pathways can inform process optimization and cost management. As a manufacturer, we leverage optimized synthesis routes to ensure consistent quality and supply.

Applications Driving its Importance: The versatility of 4-Chlorobenzaldehyde stems from its widespread application as an intermediate. In the agrochemical industry, it is a vital precursor for fungicides (e.g., tebuconazole), plant growth regulators (e.g., uniconazole), and insecticides (e.g., chlorfenapyr). For pharmaceutical research and development, it serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) like chlormezanone and various amino acid derivatives. Its utility also extends to the dye industry, where it is used in the production of specific dyes and optical brighteners. For R&D scientists requiring these specific functional groups, sourcing high-purity 4-Chlorobenzaldehyde from a reliable supplier is essential.
