Uses:

2,6-Diisopropylaniline (DIPA) — CAS 24544-04-5, EINECS 246-305-5, molecular formula C₁₂H₁₉N, MW 177.29. It is a sterically hindered aromatic amine: an aniline ring carrying an isopropyl group at both ortho positions (2 and 6). Common synonyms include 2,6-diisopropylphenylamine, 2,6-bis(1-methylethyl)benzenamine, and DIPA.

Key physical data: colorless to pale-yellow (sometimes light red/yellow) oily liquid; m.p. −45 °C; b.p. 257 °C; density 0.94 g/mL (25 °C); refractive index n²⁰/D ≈ 1.532; flash point ~123 °C; water solubility <0.2 g/L; soluble in benzene, toluene, ethanol. Typical commercial assay: technical grade ≥90–94%, reagent grade ≥97–98%. HS code 29214980.

Because of the two ortho isopropyl groups, the –NH₂ is strongly shielded: DIPA is less basic and far less nucleophilic than plain aniline, and it resists unwanted side reactions such as over-alkylation or oxidation at nitrogen. This "bulky-but-stable" character is exactly why it is valuable.

Main uses

1. Agrochemical intermediate (largest volume use)

Key intermediate for diafenthiuron, a thiourea-type acaricide/insecticide used on cotton, vegetables and fruit trees.

Used in synthesizing herbicides, fungicides and other acaricides (via nitration, isocyanate/thioisocyanate and thiourea chemistry).

Route note: it is made by alkylating aniline with propylene (or by aminating 2,6-diisopropylphenol), so its supply is tied to aniline/propylene chains.

2. Ligand & catalyst building block (highest value-added use)

Precursor to IPr / SIPr N-heterocyclic carbenes (1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) and imidazolium salts (e.g., IPr·HCl, CAS 250285-32-6). These ligands are standard in Grubbs-type olefin metathesis, Buchwald–Hartwig amination, Suzuki coupling, α-arylation and many Pd/Ni/Ru/Cu catalytic systems.

Also used for Schiff-base proligands, NSN-donor ligands, naphthalene diimide organocatalysts, and various academic/research-grade complexes.

3. Polymers, resins & additives

Intermediate to carbodiimides used as hydrolysis stabilizers (e.g., in polyesters/PBAT, polyurethanes), plus RIM polyurethane systems, synthetic resins and epoxy curing agents.

Antioxidant/stabilizer intermediates; blowing-agent-related additives that improve mechanical strength and thermal stability of plastics.

Note: it can appear as a non-intentionally added substance (NIAS) in biodegradable mulching films, so residue testing is sometimes required.

4. Pharmaceuticals, dyes & fine chemicals

Intermediate in antihypertensive APIs and other nitrogen-containing actives.

Building block for reactive dyes/pigments, dye intermediates, and some food-additive/sweetener intermediates.

General lab use as a hindered amine/base scavenger and condensation partner.

Selling points (why buyers choose it / how to position it)

Product-inherent advantages

Strong steric hindrance + moderated basicity → higher reaction selectivity, fewer by-products and cleaner downstream purification, especially in acylation/isocyanate and metal-ligand synthesis.

Liquid at room temperature (m.p. −45 °C) → easy pumping, metering and charging; no melting/dust issues compared with solid anilines.

Low volatility & low water solubility (vapour pressure <0.01 mmHg at 20 °C) → lower evaporative loss and easier aqueous work-up/waste handling.

Versatility: one molecule serves agrochemicals, pharma, dyes, polymers and high-end catalysis—broad customer base and multiple demand drivers.

Established, scalable route from commodity aniline + propylene → stable cost structure and good availability in Asia (China/India).

Commercial/quality angles buyers actually check

Assay/purity tiering: offer ≥90% (technical), ≥94–95% (agro grade) and ≥97–99% (pharma/ligand grade); specify water ≤0.2%, specific impurities (e.g., 2-isopropylaniline, 2,4-/2,5-diisopropyl isomers, aniline residue) and color (APHA).

Low-color, low-moisture batches are critical for NHC/ligand and pharma customers; provide GC traces and COA per lot.

Packaging: 200 kg drum or IBC/tank; nitrogen blanketing, dark place, cool & dry storage to prevent darkening/oxidation.

Compliance documentation: SDS, TSCA status, REACH inquiry/registration status, aquatic-hazard classification (H319 Eye Irrit. 2; H412 Aquatic Chronic 3), and transport classification (combustible liquid).

Competitive levers: price vs. Sigma/Merck reagent packs (which run very high per kg), shorter lead time, custom synthesis of derivatives (4-phenoxy-2,6-diisopropylaniline, 2,6-diisopropylphenyl isocyanate, IPr·HCl), and sample-for-testing policy.

Safety & handling notes

Aromatic amine; harmful if swallowed/in contact with skin, causes eye irritation, and harmful to aquatic life with long-lasting effects. Use gloves, eye protection and ventilation; avoid release to waterways. Store sealed, protected from light/air. Always confirm current SDS and local regulations (REACH/TSCA/China hazardous-chemicals list) before shipping.
