CAS NO.: 97-99-4
Appearance: Has micro smell and has hygroscopicity, can miscible with water, alcohol, acetone, chloroform and benzene, immiscible with paraffin hydrocarbon.

DETB is an excellent solvent with low toxicity. Because it has two groups with strong solubility in chemical structure - lipophilic covalent ether bond and hydrophilic alcohol hydroxyl, it can dissolve both hydrophobic and water-soluble compounds, so it is called "universal solvent".

Colorless, transparent liquid with a pleasant smell.
