2,3-Dimethylaniline (2,3-xylidine, CAS 87-59-2) is an aromatic amine used as a core intermediate in specialty chemical manufacturing — notably dye and pigment synthesis, hindered-phenol antioxidant intermediates, polymer and resin chemistry, and other downstream specialty processes. Commercial material is supplied in multiple grades with lot COA and SDS for supplier qualification and incoming quality control.

Storage & Handling

Store in original, tightly closed containers in a cool, dry, well-ventilated area away from strong oxidizers and acids. Protect from heat and ignition sources; recommended storage is below 30 °C. Use closed transfer, local exhaust ventilation and appropriate PPE (chemical-resistant gloves, goggles and respiratory protection where required). Retain lot COA and SDS with each shipment and follow SDS for emergency response.

FAQs

Q1: What purity is recommended for dye intermediate synthesis?

A1: High-purity grades (≥98%) with low isomeric impurity and low moisture are recommended to minimise side-reactions and color variation.

Q2: What packaging is typical for dye manufacturers?

A2: Drum (180-250 kg) or IBC packaging for production scale; 25 kg drums/pails for batch operations.

Q3: Are analytical reference standards available?

A3: Yes — suppliers typically provide small lab packs with COA for qualification.
