Unlocking Color: The Chemical Properties of 5-Methyl-o-anisidine (CAS 120-71-8)
For chemists and formulators in the colorants industry, a deep understanding of the chemical properties of intermediates is crucial for successful product development. 5-Methyl-o-anisidine, known by its CAS number 120-71-8, is a prime example of an organic compound whose specific molecular characteristics enable a vast array of color applications. As a reputable manufacturer and supplier in China, we pride ourselves on offering this vital intermediate with exceptional purity and detailed technical specifications.
The chemical structure of 5-Methyl-o-anisidine features an aniline core substituted with a methoxy group (-OCH3) and a methyl group (-CH3). This arrangement dictates its reactivity, making it an excellent building block for azo dyes through diazotization and coupling reactions. The presence of the electron-donating methoxy group and the methyl group influences the electron density of the aromatic ring and the amino group, affecting the spectral properties of the resulting dyes. For R&D scientists, grasping these nuances is key to tailoring color characteristics such as hue, intensity, and fastness.
With a high assay of ≥99.0%, our 5-Methyl-o-anisidine ensures that reactions proceed with high efficiency and minimal by-products. Its melting point typically falls within the range of 49-52°C, and it appears as light red crystals. This physical form is convenient for handling and weighing in industrial settings. The compound's solubility characteristics, being slightly soluble in hot water but more soluble in organic solvents, also play a role in its processing and application in various synthesis pathways.
The utility of 5-Methyl-o-anisidine as a dye intermediate is well-documented. It is a key component in the synthesis of direct dyes like C.I. 29050, 29065, and 27885, which are crucial for textile applications on cotton and rayon. In the realm of acid dyes, it contributes to the formation of C.I. 14940 and 14965, important for wool, silk, and nylon. Furthermore, its role in creating disperse dyes like Disperse Scarlet GC highlights its importance in coloring synthetic fibers such as polyester. Purchasing this intermediate from a reliable Chinese manufacturer ensures that these critical dye classes can be consistently produced with desired color properties.
