For research and development scientists pushing the boundaries of chemistry, a thorough understanding of the properties of their starting materials is fundamental. Butylamine (CAS 109-73-9), a primary aliphatic amine, is a widely used compound in organic synthesis and various research applications. Delving into its chemical and physical characteristics is crucial for designing effective reaction pathways, optimizing experimental conditions, and ensuring the success of novel compound development.

Butylamine, also known as 1-aminobutane, is characterized by its molecular formula C4H11N and a molecular weight of approximately 73.14 g/mol. As a primary amine, it exhibits typical amine reactivity, acting as a base and a nucleophile. Its basicity (pKa of the conjugate acid is around 10.77) allows it to react with acids to form salts and participate in reactions requiring a basic catalyst or scavenger. The presence of the amine group also makes it reactive towards electrophiles, such as acyl halides, anhydrides, and isocyanates, forming amides and ureas, respectively.

Physically, Butylamine is a clear, colorless liquid at room temperature. It possesses a distinct, pungent, ammoniacal or fish-like odor, with an odor threshold that is relatively low, indicating its detectability even at low concentrations. Its boiling point is approximately 78°C, and it has a melting point of -49°C, indicating it remains liquid over a wide temperature range relevant for laboratory synthesis. The density of Butylamine is around 0.74 g/mL at 25°C, meaning it is less dense than water. Its miscibility with water is notable; it readily dissolves in water, forming basic solutions, which is a characteristic property of many lower molecular weight amines.

The flammability of Butylamine is a significant safety consideration. It has a low flash point (around 30°F or -1.1°C), classifying it as a highly flammable liquid. This necessitates careful handling in well-ventilated areas, away from ignition sources, and adherence to appropriate laboratory safety protocols. Its vapor pressure is also notable, contributing to its flammability risk and potential for inhalation exposure.
