Product Description
Propionyl Chloride | Premium Acylating Agent
Product Overview
Propionyl Chloride is a clear, colorless to pale yellow, highly volatile, and flammable liquid. In advanced organic synthesis, it is universally recognized as a premier acylating agent, utilized to introduce the propionyl group into alcohols and amines. Its exceptional reactivity makes it an indispensable building block in the global pharmaceutical, agrochemical, and specialty polymer industries.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we supply ultra-high-purity Propionyl Chloride (≥ 99.5%) specifically engineered for Contract Research Organizations (CROs) and industrial API manufacturers. Operating rigorously under Class 3 / 8 Dangerous Goods protocols, we ensure our product is packaged under strict, moisture-free Nitrogen blanketing to guarantee flawless reactivity upon arrival.
Technical Specifications (COA)
To ensure clean reaction profiles and high yields, trace moisture and free acid must be strictly minimized. Typical specifications:
| Purity | ≥ 99.5% |
|---|---|
| Propionic Acid | ≤ 0.3% |
| Free Chlorine / Phosgene | ≤ 0.05% |
| Boiling Point | 77 - 79°C |
| Density (at 20°C) | ~ 1.059 g/cm³ |
Key Applications
- Pharmaceutical Intermediates: The core acylating reagent utilized in the synthesis of numerous Active Pharmaceutical Ingredients (APIs) and specialized prodrugs.
- Agrochemical Synthesis: A critical building block for the large-scale production of high-performance systemic herbicides and pesticides.
- Polymerization Initiators: Reacted with peroxides to manufacture specialized peroxyesters, highly efficient radical initiators for plastics.
- Flavors & Fragrances: Used as an intermediate to synthesize specific propionate esters.
🔬 Superior Yields in Propionylation
When synthesizing complex APIs or agrochemicals, managing unwanted byproducts is critical. Our highly purified Propionyl Chloride minimizes free Propionic Acid (≤ 0.3%), ensuring that your acylation or esterification reactions proceed with maximum stoichiometric efficiency, reducing downstream purification costs and boosting your overall batch yield.
Strict Anti-Corrosive DG Packaging
Because Propionyl Chloride is highly flammable and reacts violently with ambient moisture, our packaging ensures absolute safety during ocean transit:
- 200 KG / 250 KG Heavy-duty UN-approved Steel Drums with specialized anti-corrosive inner linings, tightly sealed and purged with dry Nitrogen.
- ISO TANKS available for massive bulk liquid procurement.
⚠️ Safety & Transport Information (Class 3 / 8 DG)
- Transport Classification: Classified as Class 3 (Flammable) with Subsidiary Risk 8 (Corrosive).
- UN Number: UN 1815 | Packing Group: II
- Handling Precautions: EXTREME DANGER. Highly flammable. Reacts violently with water to form corrosive HCl gas. Causes severe burns. Operators MUST handle strictly inside a fume hood wearing full hazmat gear. Store in a cool, strictly dry, explosion-proof DG facility.
