At Ningbo Inno Pharmchem Co., Ltd., understanding the fundamental properties and synthesis of chemical intermediates is paramount to serving our clients effectively. 2-Methylquinoline (CAS 91-63-4), also known as Quinaldine, is a prime example of a compound whose physicochemical characteristics dictate its wide-ranging industrial utility. This knowledge allows us to provide tailored solutions and high-quality products for specific applications.

Chemically, 2-Methylquinoline is a derivative of quinoline, characterized by a methyl group at the second position of the quinoline ring. Its molecular formula is C10H9N, with a molecular weight of approximately 143.19 g/mol. As described in various sources, it typically appears as a light yellow to colorless oily liquid. Its physical properties are noteworthy: it has a melting point around -2°C and a boiling point of approximately 248°C at atmospheric pressure. The density is around 1.058 g/mL at 25°C. These properties, such as its liquid state at room temperature and relatively high boiling point, make it suitable for processes requiring liquid handling and stable performance under moderate heating.

The purity of 2-Methylquinoline is a critical factor for its performance in different applications. Suppliers often offer it in grades ranging from 87% to 99% purity, catering to diverse industrial needs. For instance, higher purity grades are often preferred for pharmaceutical synthesis and demanding organic synthesis applications where impurities could affect reaction yields or final product quality. The ability to buy 2-Methylquinoline in these various grades ensures that manufacturers can select the most cost-effective and performance-appropriate option.

The synthesis of 2-Methylquinoline typically involves condensation reactions, most famously the Skraup synthesis or variations thereof, which react aniline with alpha,beta-unsaturated aldehydes or ketones in the presence of an acid catalyst and an oxidizing agent. For 2-Methylquinoline specifically, a common method involves the reaction of aniline with crotonaldehyde. These synthesis routes are well-established and allow for large-scale industrial production to meet market demand. The efficiency and cost-effectiveness of these synthesis methods are key to the commercial availability of 2-Methylquinoline.

Understanding these scientific underpinnings allows Ningbo Inno Pharmchem Co., Ltd. to position 2-Methylquinoline as a cornerstone product for many industries. Its reliable supply and consistent quality are vital for manufacturers engaged in creating pharmaceuticals, dyes, flavors, and other specialized chemicals. We are dedicated to providing detailed technical information and support to our clients, ensuring they can fully leverage the potential of this indispensable compound.
