Basic Information

Product Name: 4,4'-(1,3-Phenylenediisopropylidene)bisaniline; Alias: Bisaniline M, α,α'-bis(4-aminophenyl)-1,3-diisopropylbenzene, 1,3-Bis(2-(4-aminophenyl)-2-propyl)benzene, 4,4'-(1,3-Phenylene diisopropylidene)bisaniline

CAS Number: 2687-27-6 (MDL: MFCD00274255; PubChem Substance ID: 135726894, 24868249; Reaxys Registry Number: 2159385)

Molecular Formula: C??H??N?

Molecular Weight: 344.49 g/mol (theoretical value)

Structural Formula: C?H?[C(CH?)?C?H?NH?]? (an aromatic diamine compound, with a central 1,3-phenylene group connected to two isopropylidene bridges, each linking to a terminal 4-aminophenyl group, containing aromatic rings and primary amine functional groups)

Classification: Aromatic diamine, organic intermediate, polymer monomer, chemical raw material, research reagent, high-performance material precursor

Physical & Chemical Properties

4,4'-(1,3-Phenylenediisopropylidene)bisaniline is a white to light yellow powder or crystalline solid, odorless, and practically insoluble in water; soluble in toluene, and slightly soluble in other organic solvents such as ethanol and acetone. It is stable under normal temperature and pressure, but is sensitive to light and moisture—long-term exposure to light may cause slight discoloration, and contact with moisture for a long time may affect its purity. Its density is 1.08±0.1 g/cm3 (25°C, predicted), boiling point is 520.0±40.0°C at 760 mmHg (predicted), melting point is 110-117°C (literature value, mainly 113-117°C), and vapor pressure is <0.0001 mmHg at 25°C with a LogP of 6.8 at 20°C. It has no obvious hygroscopicity, but it needs to be stored in a cool, dry and dark environment to avoid impurity accumulation and performance degradation.

Key physical and chemical parameters are detailed in the specification table below, meeting the requirements of high-purity industrial grade, research grade and reagent grade.

Main Uses

4,4'-(1,3-Phenylenediisopropylidene)bisaniline (Bisaniline M) is an important aromatic diamine monomer, mainly used as a building block in polymer synthesis and related research fields, with broad application prospects in materials science and chemical industry:

Polymer Industry: Used as a key monomer for the synthesis of high-performance polymers, including polyimides, polyureas, and epoxy resins. Its rigid aromatic structure can improve the thermal stability, mechanical strength and chemical inertness of the resulting polymers, which are widely used in the preparation of high-temperature resistant materials, engineering plastics, and composite materials.
Chemical Intermediate: Used as an intermediate in organic synthesis, for the preparation of various aromatic compounds, Schiff bases, and other derivatives. It can be used in the synthesis of dyes, pigments, and fine chemicals, and plays an important role in the fine chemical industry.
Research & Laboratory Application: Used as a research reagent in materials science, polymer chemistry, and organic synthesis experiments, including polymer monomer performance testing, polymerization reaction mechanism research, and in vitro material performance evaluation. It is suitable for laboratory research and small-batch experimental production.
High-performance Material Preparation: Used in the preparation of specialized materials such as high-temperature resistant coatings, adhesives, and filtration membranes. These materials are widely used in aerospace, electronic equipment, and industrial manufacturing fields due to their excellent performance.

Packaging & Storage

Packaging Method

Lab/Research Grade: 10mg, 1g, 5g, 10g sealed glass bottles or aluminum foil bags (filled with inert gas); 100g, 500g HDPE plastic bottles with PTFE liners, suitable for laboratory research and small-batch testing.

Industrial Grade & Reagent Grade: 1kg aluminum foil bags, 5kg, 25kg cardboard drums or galvanized iron drums with PTFE liners and nitrogen-sealed; customized packaging available per customer requirements, complying with industrial raw material and reagent packaging specifications.

Storage Method

Store in a cool, dry, dark, and well-ventilated warehouse at a temperature of <15°C (cool storage recommended). Keep containers tightly sealed and protected from light to prevent moisture absorption, discoloration and purity reduction. Avoid contact with strong oxidants, strong acids and strong bases; keep away from fire, heat sources, and direct sunlight. It is sensitive to light and moisture, so strict moisture-proof and anti-light measures must be taken. Shelf life is 24 months under standard sealed, cool, and dry storage conditions.
