What is the relationship to N-ethyl-N-benzylaniline?
The two are structurally similar: this product carries one additional methyl group at the 3-position of the ring (CAS 119-94-8, molecular formula C16H19N), while N-ethyl-N-benzylaniline has none (CAS 92-59-1, C15H17N); methyl substitution shifts the dye shade toward red or purple (finished-dye performance is subject to testing of the finished dye). Distinguish the two by CAS number in inquiries. The two differ in molecular weight by about 14 (CH2), which can serve as a reference checkpoint when verifying incoming goods.
How does methyl substitution affect shade?
The methyl substituent on the m-toluidine scaffold modulates dye shade, shifting it toward red or purple; the specific shade is subject to testing of the finished dye.
Which dye types are the main downstream?
Triphenylmethane basic dyes and certain azo cationic dyes, with the resulting varieties used for acrylic fiber dyeing; the correspondence to specific varieties follows the customer's synthesis routes.
What are the assay and impurity specifications?
Assay (GC) ≥98.0%, N-ethyl-m-toluidine ≤0.5%, N,N-diethyl-m-toluidine ≤0.5%, moisture ≤0.2% (see specifications); production and release inspection follow the specifications on this page, and batch data is confirmed with our sales team during inquiry.
What packaging and order quantities are available?
Standard packaging is a 200 kg iron drum, and custom packaging is available. Sample arrangements and order quantities can be discussed during inquiry; regular batches are produced against the order schedule.
What are the storage and transport requirements?
Store sealed in a cool, dry, well-ventilated place away from heat, sparks and open flames, avoiding direct sunlight; see specifications for flash point and related data. Transport classification follows the goods transport appraisal report and the carrier's requirements.
