For chemists, R&D scientists, and product formulators, a thorough understanding of a chemical's properties is fundamental to its successful application. Isobutyl Butyrate (CAS 539-90-2), a versatile ester, possesses a specific set of characteristics that dictate its performance across various industries. As a chemical manufacturer and supplier, we provide detailed insights into these specifications to aid your product development and procurement decisions.

Isobutyl Butyrate is characterized by its physical appearance: a colorless liquid. This clarity is often an indicator of its purity, a critical factor for its use in sensitive applications. Speaking of purity, our Isobutyl Butyrate typically meets a high standard, with an assay of ≥98% by GC (Gas Chromatography). This level of purity ensures reliable and consistent results in formulations where precise chemical composition is crucial.

The molecular details of Isobutyl Butyrate are also key to understanding its behavior. Its molecular formula is C8H16O2, and its molecular weight is approximately 144.21 g/mol. These specifications are important for stoichiometric calculations in chemical syntheses and for regulatory compliance.

Key physical properties that influence its applications include its boiling point, typically around 155-157°C, and its flash point, which is approximately 42°C (closed cup). These figures provide essential information for safe handling, storage, and processing, particularly in industrial settings. Its solubility profile is also noteworthy: while insoluble in water, it is miscible with ethanol and oils, making it a versatile component in various solvent systems and formulations. This property is particularly valuable for its use as an industrial solvent in coatings and paints.

The odor profile of Isobutyl Butyrate—described as sweet and fruity—is a primary driver for its use in the flavor and fragrance sectors. Understanding its sensory attributes alongside its chemical specifications allows formulators to effectively integrate it into their products. For businesses looking to purchase Isobutyl Butyrate, reviewing these technical details is an important step in ensuring it meets their application requirements.
