Application

4 Methylacetophenone is a versatile aromatic ketone with broad applications across fragrance, flavor, pharmaceutical, and chemical synthesis sectors.

In the fragrance industry, this compound is a key ingredient in perfumes, soaps, lotions, and personal care products, providing a sweet, floral scent reminiscent of jasmine, hawthorn, and mimosa. It is particularly valued for blossom notes in mimosa and hawthorn type perfumes for soap applications. Its odor profile combines hawthorn, sweet mimosa, coumarin, cherry, and acetophenone notes, making it a versatile fixative and modifier. The compound occurs naturally in mango, tomato, and orange.

In the flavor industry, 4 methylacetophenone is used as a flavoring agent, particularly in desserts, confections, and fruit flavored products, imparting a sweet, strawberry like taste. It is listed as FEMA 2677 and JECFA 807 for food use.

In pharmaceutical and organic synthesis, this compound serves as a starting material in the production of various pharmaceuticals, including the anti inflammatory drug Celecoxib. It is utilized in studies of the Baeyer Villiger reaction, which converts ketones to esters or lactones for the synthesis of dyes and pharmaceutical intermediates. It also finds application in the synthesis of functionalized terpolymers for electronic devices and biological materials. In agrochemical manufacturing, it is used as an intermediate for herbicides and other crop protection agents.

FAQ

Q1 How should 4 methylacetophenone be stored to maintain its quality?
A Store in a cool, dark place at room temperature (recommended below 15 degrees Celsius) in tightly closed containers. Protect from light and heat. Shelf life is 24 months under recommended conditions. Due to its low melting point (22 to 24 degrees Celsius), the product may solidify or become supercooled at room temperature; gentle warming may be required for transfer.

Q2 What purity grades do you supply?
A Standard grade is 99.0 percent minimum by GC. We also supply 99.5 percent grade for pharmaceutical intermediate applications and FCC grade (95.0 percent minimum) for flavor and fragrance use.

Q3 Is 4 methylacetophenone soluble in water?
A It is practically insoluble in water (0.37 g per L at 15 degrees Celsius). It is soluble in ethanol, diethyl ether, benzene, chloroform, propylene glycol, and most organic solvents.

Q4 Do you provide sample quantities for fragrance development?
A Yes, free samples of 100 mL are available for qualified US companies. Shipping fee applies for small quantities.

Q5 What are the common impurities and how do you control them?
A Key impurities include related ketones and residual solvents. Our specification limits total impurities below 0.5 percent. Full impurity profiling is provided per batch.

Q6 Is 4 methylacetophenone approved for use as a food flavoring?
A Yes, it is listed as FEMA 2677 and JECFA 807. It is approved for use as a flavoring agent in food products. Please request our regulatory package for your specific application and compliance documentation.
