【CAS】102-76-1 Molecular formula:C9H14O6 Relative molecular mass:218.2039
Structural formula:
一．Product Property：
Colorless and transparent oily liquid, slightly bitter in taste, slightly soluble in water, soluble in various organic solvents, having the general properties of esters. Boiling point 258℃ (0.101 MPa), flash point 138℃ (closed cup), melting point 3℃. Strong solvent effect, which can give the products good flexibility.
