English description（英文原文，共 1370 字符）
Product Name:Formyl-PEG-t-butyl propionate
English Name:Formyl-PEG-t-butyl propionate
CAS No.:2086688-99-3
Aliases:HCO-PEG-TBA, Aldehyde-PEG-t-butyl propionate, Formic acid-PEG-t-butyl propionate
Molecular Formula:OHC-(C2H4O)n-CH2CH2COOC(CH3)3
Physical Properties:White to off-white solid or viscous liquid depending on PEG molecular weight; freely soluble in water, ethanol, DMSO, dichloromethane, etc.; contains an aldehyde group capable of reductive amination with primary amines; hygroscopic to some extent; should be stored sealed, protected from light and kept at low temperature.
Uses:As a bifunctional PEG derivative, the aldehyde group reacts with amino groups on proteins, peptides, nucleic acids, and other biomolecules via reductive amination for efficient bioconjugation. The tert-butyl ester at the other end can be deprotected under acidic conditions to yield a carboxyl group, enabling construction of biodegradable polymeric prodrugs, nano drug delivery systems, and biosensors.
Technical Specifications:
Appearance: white to off-white solid or viscous liquid depending on PEG molecular weight
Purity: ≥95% (HPLC)
Solubility: readily soluble in water, DMSO, DMF, dichloromethane, etc.
Storage: store sealed at -20°C, protected from light, moisture, and heat
Molecular weight: available in 1K, 2K, 5K, 10K, 20K and other custom specifications
