Germany, the United States, and China are the leading exporters of 1,8-Diazabicyclo[5.4.0]undec-7-ene, collectively accounting for over 60% of global exports in recent years, while key importing markets include South Korea, Japan, and India—driven by demand from pharmaceutical and specialty chemical manufacturing. Trade volumes have remained relatively stable since 2022, with modest growth in Asian imports coinciding with upward pressure on 1,8-Diazabicyclo[5.4.0]undec-7-ene prices amid tightening supply from major European producers.

I. Price Quotation Data
| Time Point | Quoting Entity | Specification | Origin/Delivery Location | Quotation (CNY/ton) | Packaging |
|---|---|---|---|---|---|
| 2026-09-24 | Jiangsu Xinsu New Materials Co., Ltd. | 99% (TWIN) | Jiangsu/Suzhou | 43,000 | — |
| 2026-11-04 | Jiangsu Xinsu New Materials Co., Ltd. | 99% | Jiangsu/Suzhou | 84,000 | 200 kg/drum |
| 2026-11-05 | Jiangsu Xinsu New Materials Co., Ltd. | 99% | Jiangsu/Suzhou | 84,000 | 200 kg/drum |
| 2026-11-06 | Jiangsu Xinsu New Materials Co., Ltd. | 99% | Jiangsu/Suzhou | 84,000 | 200 kg/drum |
| 2026-11-09 | Jiangsu Xinsu New Materials Co., Ltd. | 99% | Jiangsu/Suzhou | 84,000 | 200 kg/drum |
| 2026-11-10 | Jiangsu Xinsu New Materials Co., Ltd. | 99% | Jiangsu/Suzhou | 84,000 | 200 kg/drum |
**Price Fluctuation**: Prices surged from 43,000 CNY/ton in late September to 84,000 CNY/ton in November, representing an increase of approximately **95.3%**. Over the past month (November 4–10), prices have remained stable at the high level of 84,000 CNY/ton.

II. Supply-Side Market Dynamics
1. **Stable Quotations from Key Suppliers**: As the core quoting entity, Jiangsu Xinsu New Materials Co., Ltd. has locked its quotation at 84,000 CNY/ton for consecutive days since November 4, with no price adjustments, indicating a strong intention to support prices on the supply side.
2. **Continuous Tracking by 100PPI (Shengyishe)**: 100PPI has continuously published price dynamics for diazabicyclic/diazabicyclo products on November 6, 9, 10, and 11, indicating high market attention and increased trading activity for this product.
3. **Production Capacity and Inventory**: Current public information does not disclose specific changes in production capacity. However, given that quotations remain high without loosening, the supply side is likely in a state of tightness or cost-push price support.
---
III. Demand Side and Macro Environment
1. **Overall Weakness in the Chemical Sector**: According to commodity data from October 21, the ratio of gainers to losers in the chemical industry was 5%:9%, with an average change of -0.03%, indicating that the overall chemical market is under pressure. However, the counter-trend sharp rise in diazabicyclic products suggests that its demand logic is independent of bulk chemical commodities.
2. **Downstream Application Drivers**: Diazabicyclic products (such as DABCO, TBD, etc.) are mainly used in polyurethane catalysts, epoxy curing agents, pharmaceutical intermediates, and other fields. Recent demand from high-end applications such as new energy and electronic chemicals may be providing support for prices.
3. **Raw Material Cost Transmission**: Upstream basic chemical raw materials (such as methanol and acetic acid) saw weakening prices in October, yet diazabicyclic prices rose instead of falling. This indicates that the cost side is not the dominant factor; rather, the price increase is more likely driven by structural supply-demand tightness or specific downstream demand pull.

IV. Analytical Judgment
| Dimension | Judgment |
|---|---|
| **Price Trend** | Short-term high-level firmness; no signs of loosening in the past week |
| **Supply-Demand Structure** | Supply side is concentrated (single main quoting source); demand side has rigid support; supply-demand is tight |
| **Price Driver** | Not cost-driven; more likely due to supply-demand mismatch + pull from high-end downstream demand |
| **Market Sentiment** | Quoting party has locked prices for consecutive days; bullish market sentiment is strong |
---
V. Forecast
1. **Short-term (1–2 weeks)**: Prices are expected to fluctuate around the high level of 84,000 CNY/ton. Without the release of new production capacity or a sudden drop in downstream demand, there is limited room for price decline.
2. **Medium-term (1–3 months)**: Attention needs to be paid to two variables: ① whether new suppliers enter the market to break the single-quoting structure; ② changes in the prosperity of downstream industries such as polyurethane and electronic chemicals. If demand remains robust, prices may further rise; if demand weakens, the risk of high-level correction will increase.
3. **Risk Warning**: Current quotation sources are single (only Jiangsu Xinsu), with a limited sample size. Actual market transaction prices may have regional price differences. It is recommended to continuously track 100PPI benchmark prices and quotations from more suppliers to verify the true market level.

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) is a colorless to pale yellow, hygroscopic liquid with a strong, pungent odor and moderate volatility; it has a melting point of approximately –70 °C and a boiling point of 130–135 °C at 15 mmHg. It is classified as a bicyclic amidine and functions primarily as a non-nucleophilic, strong organic base. DBU is widely employed as a catalyst and reaction promoter in organic synthesis, particularly in condensation, elimination, and polymerization reactions. Its principal applications are in the production of polyurethanes, acrylic pressure-sensitive adhesives, and specialty polymers, as well as in pharmaceutical and agrochemical synthesis where controlled basicity is required.
