English description（英文原文，共 1335 字符）
Product Name:α,ω-Dipropionic acid tetraethylene glycol
English Name:α,ω-Dipropionic acid tetraethylene glycol
CAS No.:439114-13-3
Aliases:Tetraethylene glycol dipropionic acid, Bis-PEG4-acid, Carboxy-PEG4-carboxylic acid
Molecular Formula:C14H26O9
Physical Properties:It is a colorless to slight yellow transparent viscous liquid at room temperature. It is soluble in water, ethanol, dimethyl sulfoxide, and N,N-dimethylformamide, but insoluble in petroleum ether. The estimated density is about 1.18 g/cm³, the predicted boiling point is about 480°C, and the flash point is above 150°C. It is hygroscopic and should be stored sealed, protected from light, in a dry place.
Uses:This compound is a polyethylene glycol (PEG) derivative bearing carboxylic acid groups at both terminals. It is a commonly used bifunctional PEG crosslinker for the synthesis of antibody-drug conjugates (ADCs), protein/peptide modification, and surface functionalization of nanomaterials. It can also serve as an intermediate for the preparation of biodegradable polymers.
Technical Specifications:
Purity: ≥95%
Appearance: colorless to slight yellow transparent viscous liquid
Molecular weight: 338.35
Solubility: soluble in water, ethanol, DMF, and DMSO; insoluble in ethers and hydrocarbons
Storage: keep sealed at 2–8°C, protected from light
