N,N-Dimethylaniline (DMA), identified by CAS number 121-69-7, is a tertiary amine that has carved out a significant niche in the chemical industry due to its distinct properties and wide-ranging utility. As a chemical compound, its precise molecular formula is C8H11N, with a molecular weight of 121.18 g/mol. Understanding the N,N-Dimethylaniline properties is fundamental to appreciating its industrial value. Typically appearing as a straw to brown-colored oily liquid, DMA possesses a characteristic amine-like odor, which is a common trait among aniline derivatives.

Physically, DMA exhibits a melting point between 1.5 to 2.5°C and a boiling point of approximately 193-194°C. Its refractive index, n20/D, is noted as 1.557, and it has a flash point of 158°F, classifying it as a combustible material. While insoluble in water, DMA demonstrates good solubility in common organic solvents such as ethanol, chloroform, ether, and aromatic hydrocarbons. This solubility profile makes it a convenient reagent and solvent in various organic synthesis processes. The N,N-Dimethylaniline applications are vast, stemming directly from these physicochemical characteristics.

The most prominent N,N-Dimethylaniline applications lie in its role as a key intermediate for dyes. It is a crucial precursor in the synthesis of triphenylmethane dyes, including vibrant colorants like Basic Green 4 and Basic Violet 1, and contributes to the production of various azo dyes. The demand for these dyes in the textile, printing, and coatings industries ensures a consistent market for high-quality DMA. For businesses in these sectors, securing a reliable N,N-Dimethylaniline supplier in China is vital for maintaining production continuity and product quality.

Furthermore, DMA is an important intermediate in the pharmaceutical industry. It is used in the manufacturing of essential medicines such as cefazolin V and sulfamonomethoxine, contributing to the production of critical therapeutic agents. The stringent quality requirements in pharmaceutical manufacturing mean that sourcing pharmaceutical-grade DMA from trusted manufacturers is paramount. Companies looking to buy N,N-Dimethylaniline for these applications must prioritize suppliers who adhere to rigorous quality control standards.

Beyond these major uses, DMA serves as a specialty industrial solvent and an activator or promoter in the curing of polyester and vinyl ester resins. Its ability to accelerate resin curing is particularly valuable in the production of fiberglass-reinforced plastics and coatings, enhancing both processing speed and the mechanical properties of the finished products. This versatility further solidifies its position as a valuable industrial chemical.

The synthesis of DMA typically involves the alkylation of aniline with methanol, often facilitated by acid catalysts. Industrial N,N-Dimethylaniline production focuses on efficient and cost-effective methods to meet global demand. Understanding the N,N-Dimethylaniline price and availability from various manufacturers is key for procurement professionals. Partnering with a reputable N,N-Dimethylaniline manufacturer in China, like NINGBO INNO PHARMCHEM CO.,LTD., offers a strategic advantage in terms of product quality, competitive pricing, and dependable supply chains.
