For professionals in the chemical and pharmaceutical sectors, a thorough understanding of a compound's physicochemical properties is fundamental to its effective utilization. 4-Chloro-6-methylquinoline (CAS 18436-71-0) is no exception. This important pharmaceutical intermediate, frequently sought after by researchers and manufacturers, possesses distinct characteristics that dictate its handling, storage, and reactivity in synthesis processes. As a leading supplier of this compound from China, we aim to provide clarity on these critical attributes.

Visually, 4-Chloro-6-methylquinoline typically presents as an off-white to pale yellow crystalline powder. This appearance is a key initial indicator of its purity and physical state. The crystalline nature suggests a well-defined molecular structure, which is crucial for reproducible results in chemical reactions. The subtle color variation from off-white to pale yellow often relates to minor impurities or specific manufacturing batches, but high-purity grades will aim for the lighter end of this spectrum. For buyers sourcing this material, asking for detailed batch analysis reports is always recommended.

The melting point of 4-Chloro-6-methylquinoline is generally reported in the range of 90-92°C. This specific melting range is a significant physical parameter that aids in its identification and purity assessment. A sharp melting point within this narrow range typically indicates a highly pure substance. Conversely, a broad or depressed melting range might suggest the presence of impurities. Understanding this property is vital for R&D scientists when designing reaction conditions or purification steps.

Solubility is another critical physicochemical property. 4-Chloro-6-methylquinoline exhibits good solubility in common organic solvents such as ethanol, acetone, and DMSO. This solubility profile makes it amenable to a wide range of reaction media and work-up procedures. However, it is notably insoluble in water, a characteristic that influences its extraction and isolation methods, particularly during synthesis and purification. When planning experimental procedures, selecting appropriate solvents based on this information is key.
