Diethyl Phthalate Bulk Price 2026: Market Outlook, Purity Standards & Sourcing Strategy
- Projected Diethyl Phthalate bulk prices in 2026 reflect stable raw material costs and increased demand in regulated markets.
- Industrial purity ≥99% (GC) and full COA documentation are critical for pharma and agrochemical applications.
- NINGBO INNO PHARMCHEM CO.,LTD. offers scalable supply of high-yield Diethyl Phthalate with GMP-aligned manufacturing.
As the global chemical market prepares for 2026, procurement professionals and R&D managers are actively evaluating the Diethyl Phthalate bulk price outlook for CAS 84-66-2—a key intermediate widely used in pesticides, plasticizers, and fragrance formulations. Also known as benzene-1,2-dicarboxylic acid diethyl ester or diethyl ortho-phthalate, this compound is synthesized via esterification of phthalic anhydride with ethanol, yielding the diethyl ester of phthalic acid with high efficiency under optimized catalytic conditions.
Global Market Price Trends for Diethyl Phthalate in 2026
Historical export data from 2022–2023 indicates that bulk pricing for Diethyl Phthalate has remained relatively stable across major markets, with FOB India rates ranging between USD 1,530–2,270 per metric ton depending on destination, regulatory requirements, and order volume. Notably, shipments to the United States and EU nations—classified as "regulated markets"—command premium pricing due to stringent documentation (e.g., TSCA, REACH compliance) and higher purity thresholds.
Looking ahead to 2026, several macroeconomic and supply-chain factors will influence the bulk price:
- Feedstock Stability: Ethanol and phthalic anhydride—core raw materials—have seen moderated volatility post-2023, supporting predictable production economics.
- Regulatory Pressure: Increasing scrutiny on phthalate derivatives in consumer goods may shift demand toward certified industrial-grade batches with full traceability.
- Regional Demand Shifts: Growth in Southeast Asia (Indonesia, Thailand) and Latin America (Mexico, Colombia) is driving containerized exports, while Middle Eastern and African markets favor smaller drum quantities.
Based on current trajectory, the 2026 FOB China bulk price for pharma-grade Diethyl Phthalate is projected to range between USD 1,650–1,850/MT for orders exceeding 20 MT, assuming standard industrial purity (≥99% by GC).
Technical Specifications & Industrial Purity Requirements
For B2B buyers, technical consistency is non-negotiable. High-performance applications—particularly in pesticide intermediates—require strict adherence to physicochemical benchmarks. The following table outlines standard specifications for commercial-grade material:
| Parameter | Specification |
|---|---|
| CAS Number | 84-66-2 |
| Chemical Name | Diethyl benzene-1,2-dicarboxylate |
| Assay (GC) | ≥99.0% |
| Density (20°C) | 1.118 g/mL |
| Boiling Point | 298–299°C |
| Refractive Index (n²⁰D) | 1.5010–1.5030 |
| Flash Point | 156°C |
| Packaging | ISO tank, IBC tote, or 200L HDPE drum |
Every batch must be accompanied by a Certificate of Analysis (COA) verifying identity, assay, and residual solvent levels. NINGBO INNO PHARMCHEM CO.,LTD. provides full analytical dossiers—including GC chromatograms and IR spectral validation—to ensure seamless integration into downstream synthesis workflows.
Optimized Synthesis Route & Manufacturing Scalability
The industrial production of Diethyl Phthalate hinges on a robust synthesis route that maximizes reaction yield while minimizing byproducts. The standard process involves:
- Esterification of phthalic anhydride with absolute ethanol under acid catalysis (e.g., sulfuric acid or p-toluenesulfonic acid).
- Azeotropic removal of water to drive equilibrium toward ester formation.
- Neutralization, washing, and vacuum distillation to achieve ≥99% purity.
NINGBO INNO PHARMCHEM CO.,LTD., as a premier global manufacturer, operates GMP-compliant facilities with multi-ton batch capacity, enabling consistent output of high-purity Diethyl Phthalate tailored for agrochemical and specialty chemical applications. Their process control ensures minimal diester impurities and low acidity (<0.1 mg KOH/g), critical for sensitive formulations.
When sourcing high-purity Diethyl Phthalate, buyers should prioritize suppliers with vertical integration, rigorous QC protocols, and proven export experience to regulated jurisdictions.
Strategic Sourcing Recommendations for 2026
To secure cost-effective, compliant supply in 2026, consider the following:
- Volume Commitments: Annual contracts for >100 MT can lock in favorable rates and mitigate spot-market fluctuations.
- Documentation Readiness: Ensure your supplier provides full regulatory support—TSCA, REACH, ISO, and GMP documentation upon request.
- Logistics Flexibility: Choose manufacturers offering multiple packaging formats (drums, totes, bulk tanks) and port options (Ningbo, Shanghai, Qingdao).
As a top-tier Chinese manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. combines technical excellence with competitive bulk pricing, making it a strategic partner for global enterprises seeking reliable access to high-quality Diethyl Phthalate through 2026 and beyond.
