For chemists and product developers in the B2B chemical sector, a thorough understanding of chemical intermediates is fundamental to innovation. 3-Heptanone (CAS 106-35-4), also known by synonyms such as ethyl butyl ketone or heptan-3-one, is a versatile compound that warrants close examination due to its unique properties and synthesis pathways. As a leading chemical producer, we aim to provide professionals with the detailed information needed to effectively utilize this compound.

The chemical identity of 3-Heptanone is defined by its molecular formula C7H14O and a molecular weight of approximately 114.19 g/mol. Physically, it presents as a colorless liquid, notable for its potent aroma, which is frequently described as fruity, green, and sometimes fatty or cheesy. Its physical properties include a boiling point around 146-149 °C and a flash point of approximately 46 °C, classifying it as a flammable liquid that requires careful handling.

Industrially, 3-Heptanone is primarily synthesized through a two-step process: the reductive condensation of propionaldehyde with butanone (methyl ethyl ketone) to form hept-4-en-3-one, followed by the hydrogenation of this intermediate. This manufacturing route ensures a high-purity product, making it suitable for demanding applications. Researchers and R&D scientists can rely on this well-established synthesis to procure consistent batches of 3-heptanone for their projects.

The applications of 3-Heptanone are diverse, with significant use in the flavor and fragrance industry. Its aroma profile makes it an excellent component for creating realistic cheese, melon, and banana flavors in food products. Perfumers also utilize its olfactory characteristics to add depth and complexity to fragrances. Beyond sensory applications, its utility extends to being a solvent for materials like nitrocellulose and as a key intermediate in various organic synthesis reactions. If your company is looking to buy 3-heptanone, understanding these applications will help in specifying your requirements.

Procurement professionals seeking to purchase 3-heptanone should pay close attention to the specifications provided by manufacturers. A reliable supplier will offer detailed technical data, including assay results, CAS number, and safety information. When evaluating the price of 3-heptanone, it's important to consider the scale of purchase and the supplier's location, with many reputable manufacturers based in China offering competitive bulk rates. Collaborating with a dedicated chemical manufacturer ensures access to the expertise and quality control necessary for such critical chemical intermediates.

In conclusion, 3-Heptanone is a valuable chemical intermediate with a broad spectrum of applications.
