Products Description
4-Dodecylphenol has two mainstream CAS numbers: 210555-94-5 and 27193-86-8. Both belong to para-dodecylphenol isomer mixtures with same molecular formula and molecular weight. However, they differ in alkyl branching structure, leading to different performance and application scenarios. They cannot be directly substituted. Select grade according to your formulation requirements.

FAQ
Q: Are CAS 210555-94-5 and CAS 27193-86-8 the same product?
A: No. Both belong to 4-dodecylphenol family, but the degree of alkyl branching is different, leading to different thermal stability and solubility.
Q: Could they replace each other directly in formulation?
A: Not directly interchangeable. The branching degree affects thermal stability, viscosity and oil solubility. Please carry out formulation test before substitution.
Q: What is the main raw material for producing these two dodecylphenol grades?
A: Both are synthesized by alkylation reaction of phenol and dodecene. The difference comes from different types of dodecene feedstock.
Q: What is the storage requirement for 4-dodecylphenol?
A: Store in sealed, cool, dry and ventilated warehouse. Keep away from strong oxidants, strong bases. Avoid direct sunlight.
Q: Could both grades be used to make oilfield demulsifiers?
A: Yes. 27193-86-8 is widely used for general demulsifiers; 210555-94-5 is selected for high-performance oilfield formulations.
