N,N-Diethyl-m-toluidine
N,N-Diethyl-m-toluidine (CAS: 91-67-8) is a tertiary aromatic amine supplied as a colorless to brown liquid. It is used as an intermediate for dyes and colour formers.
The diethylamino group on the activated toluene ring makes it a strong coupling and condensation partner for rhodamine-type and fluoran dyes.
Its performance depends on low colour, low mono-ethyl impurity and stable assay.
It should be stored closed under nitrogen, away from light. Typical quality points are assay by GC, colour, water and low N-ethyl-m-toluidine content.
• Dye and fluorescent colorant intermediate: building block for rhodamine and basic dyes. The activated ring gives strong condensation and good yield.
• Thermal and pressure-sensitive paper chemistry: precursor for leuco colour formers. The resulting colorants are valued for intensity and clarity.
• Fine-chemical synthesis: starting material for substituted aniline derivatives. It is also used in speciality coating colorants.
• Photographic and imaging chemicals: applied in imaging and specialty colour-forming systems that use tertiary aniline couplers.
