What is 4,4-Methylenedianiline CAS 101-77-9?

Usage restrictions:

Avoid direct contact. Local exhaust equipment should be installed in the operation area

Products exported to the European Union need to provide SDS documents and REACH test reports

Alternative solution:

It is recommended to use environmentally friendly curing agents (such as 4,4' -methylene bis (2, 6-diethylaniline), which have lower toxicity)

4,4-Methylenedianiline CAS 101-77-9 Use

Industrial curing agent

Epoxy resin curing: Endows the material with high tensile strength, heat resistance and electrical insulation

Polyurethane chain extender: Used in elastomers and waterproof materials (such as polyurea spraying process)

Chemical intermediates

Synthetic dyes (azo structure), pesticides and medicines (such as the antimalarial drug ethazine)

Restricted use range

Textiles/Leather: Do not use decomposable aromatic amine dyes (detection limit ≤20 mg/kg)

REACH Regulation: Third-party testing and certification are required (such as the ZDHC MRSL standard)

4,4-Methylenedianiline CAS 101-77-9 safety

Acute toxicity

Oral LD₅₀ in rats: 347 mg/kg (highly toxic)

Percutaneous stimulation in rabbits: 500 mg/24h (severe stimulation)

Carcinogenicity

The World Health Organization (WHO) has classified it as a Group 2B carcinogen (possibly carcinogenic to humans).

Long-term exposure may cause bladder cancer and liver cancer

Protection requirements

Operation protection: Wear a gas mask, rubber gloves, goggles and anti-toxic suit

Leakage handling: Cover with plastic sheeting and collect, avoiding contact with water (hydrolysis generates toxic gases)
