Product Name:3,6,9-Trioxaundecanedioic acid
English Name:3,6,9-Trioxaundecanedioic acid
CAS No.:518044-49-0
Aliases:Triethylene glycol dicarboxylic acid, PEG diacid (n=2), 2,2'-(Oxybis(ethane-2,1-diyl)bis(oxy))diacetic acid
Molecular Formula:C8H14O7
Physical Properties:It appears as a colorless to pale yellow viscous liquid. It is readily soluble in water, ethanol, dichloromethane and other polar solvents. The molecule bears two carboxylic acid groups and is weakly acidic. Density: about 1.30 g/cm³ (estimated); boiling point: approximately 405 °C (estimated); flash point: estimated above 110 °C.
Uses:Used as a bifunctional crosslinking agent in bioconjugation and drug delivery systems; it can form amide bonds with amine groups via its two carboxyl groups. Also used in the preparation of PEGylated derivatives, antibody-drug conjugates (ADCs), and functional biomaterials. It serves as an intermediate in organic synthesis to introduce an ethylene glycol spacer.
Technical Specifications:
Purity: ≥95% (HPLC)
Appearance: colorless to pale yellow viscous liquid
Solubility: soluble in water, ethanol, and dichloromethane
Storage: keep at 2–8 °C, sealed and protected from light
Formula: C8H14O7; Molecular weight: 222.19
