3,6,9,12,15,18,21,24-Octaoxapentacosanoic acid - Introduction

m-PEG7-CH2COOH (for polyethylene glycol formate) is a chemical molecule that has the following characteristics and properties:

Nature:
-Appearance: Colorless or light yellow solid
-Molecular formula: C10H20O8
-relative molecular mass: 276.26
-Melting point: 70-74 ° C
-Solubility: Good solubility in water
-Chemical stability: stable, not easy to decompose
-Molecular structure: The formic acid group (-COOH) and the polyethylene glycol chain (-PEG7-) are connected by a methylene group (-CH2-)

Use:
- m-PEG7-CH2COOH are widely used in the biomedical field, often used in biomedical research and pharmaceutical preparations.
-Due to its unique water solubility and biocompatibility, m-PEG7-CH2COOH are often used as drug encapsulation agents to improve drug solubility, stability and in vivo distribution.

Method:
- m-PEG7-CH2COOH can be synthesized by ethylene glycol esterification reaction. First, ethylene glycol formate is prepared by an esterification reaction between ethylene glycol and glycerin in the presence of a basic catalyst. Subsequently, the ethylene glycol formate is methylene-linked to the polyethylene glycol chain, and the m-PEG7-CH2COOH is synthesized by adjusting the reaction conditions and using appropriate reagents.

Safety Information:
- m-PEG7-CH2COOH are generally safe under regular laboratory operating conditions.
