Understanding the intrinsic chemical properties and synthesis pathways of key intermediates like m-Anisidine (CAS 536-90-3) is fundamental for any chemical professional involved in R&D, formulation, or large-scale manufacturing. Also known as 3-Methoxyaniline, this organic compound's characteristics dictate its suitability for various applications, from the vibrant world of azo dyes to the precise requirements of pharmaceutical synthesis. For those looking to buy m-Anisidine, a grasp of its chemistry ensures informed sourcing decisions.

m-Anisidine is characterized by its physical state as a liquid, typically appearing as a transparent yellow to brown color, which can darken upon exposure to air due to oxidation. Its melting point hovers around -1 to 1°C, while its boiling point is a notable 251°C, indicating its relative thermal stability for many chemical processes. The density is approximately 1.096 g/mL at 25°C. Its solubility profile is also important: it is generally soluble in organic solvents like ethanol and ether but shows limited solubility in water, a characteristic that influences its handling and reaction conditions. The pKa of 4.23 at 25°C provides insight into its basicity as an amine.

The synthesis of m-Anisidine often involves the reduction of its nitro precursor, m-nitroanisole. A common industrial method involves the methylation of m-nitrophenol to form m-nitroanisole, followed by catalytic hydrogenation or reduction using agents like iron in acidic media. This process requires careful control of reaction parameters to ensure high yields and purity, minimizing side products. For manufacturers, optimizing these synthesis routes is key to producing cost-effective, high-quality m-Anisidine suitable for demanding applications. If you're a buyer seeking this intermediate, inquire about the typical synthesis methods used by your potential m-Anisidine supplier.

The Flash point of m-Anisidine is greater than 230°F (>230 °F), which classifies it as a combustible liquid rather than a flammable one under standard conditions, but still requires appropriate safety precautions during handling and storage. Proper storage conditions, such as keeping it in a well-closed, light-resistant, dry, and cool place (often recommended at 2-8°C), are crucial to maintain its quality and prevent degradation.
