For professionals in chemical research and development, as well as procurement managers in the pharmaceutical and specialty chemical industries, a thorough understanding of a compound's properties is fundamental. 4,N,N-Trimethylaniline, identified by its CAS number 99-97-8, is a compound whose characteristics make it valuable for a range of applications. As a leading manufacturer and supplier of such intermediates, NINGBO INNO PHARMCHEM CO.,LTD. aims to provide clarity on its key attributes to aid in informed decision-making.

Physical Characteristics: Appearance and State

4,N,N-Trimethylaniline typically presents as a light yellow oily liquid. While pure samples may appear colorless, slight discoloration can occur due to minor oxidation or impurities, which is common for many aromatic amines. Its liquid state at room temperature, with a low melting point of around -25°C, ensures ease of handling and processing in most laboratory and industrial settings. The oily texture is characteristic of many aromatic compounds with alkyl substituents.

Chemical Properties and Reactivity:

• Molecular Formula and Weight: C9H13N; Molecular Weight: 135.21 g/mol. This data is crucial for stoichiometric calculations in synthesis.
• Boiling Point: Approximately 211.6°C at 760 mmHg. This relatively high boiling point indicates moderate volatility and is important for distillation and separation processes.
• Density: Around 0.9 g/cm³ at room temperature. This allows for volume-to-mass conversions.
• Solubility: It is generally insoluble in water but readily soluble in common organic solvents such as alcohol, ether, and chloroform. This property dictates its use in non-aqueous reaction media.
• Stability: While generally stable, like many amines, it can darken upon prolonged exposure to air or light, suggesting the need for appropriate storage conditions (e.g., in amber bottles, under inert atmosphere if long-term storage is required).
• Reactivity: As a tertiary aromatic amine, it exhibits nucleophilic character and can participate in various organic reactions, including electrophilic aromatic substitution and as a catalyst or co-catalyst in polymerization.

Applications Driven by Properties:

The combination of its liquid form, solubility in organic solvents, and specific reactivity makes 4,N,N-Trimethylaniline a sought-after intermediate. Its primary uses include:

• Pharmaceutical Intermediates: A key building block in the synthesis of active pharmaceutical ingredients (APIs).
• Dye Synthesis: Used in the creation of various azo dyes and pigments.
• Polymerization: Functions as an accelerator in the curing of polyesters, acrylates, and epoxy resins.
• Chemical Synthesis: Serves as a versatile reagent in a wide range of organic transformations.
