7-[3-(Chlorodimethylsilyl)Propoxy-4-Methylcoumarin - Introduction

7-[3-(Chlorodimethylsilyloxy) propoxy]-4-methylcoumarin (abbreviated as CPS) is a chemical substance with the following properties:

1. Appearance: CPS is a white solid powder, sometimes yellow.

2. Solubility: CPS is insoluble in water, but can be dissolved in organic solvents such as ethanol, dimethyl methane, etc.

3. Stability: CPS is stable and has a long life span to maintain activity.

The main uses of CPS include:

1. Preservative: Because CPS has strong antibacterial properties, it is often used as a preservative, especially in cosmetics and personal care products.

2. Coating additives: CPS can be used as thickener and surfactant in coatings to improve the viscosity and stability of coatings.

3. Chemical analysis: CPS can be used as an indicator in dye analysis to help determine the concentration of chemical substances.

Method of preparing CPS:

A common preparation method of CPS is to react 3-(chlorodimethylsilyloxy) propionic acid with 4-methylcoumarin. The reaction is usually carried out in a solvent such as dimethylformamide (DMF) or a chlorinated hydrocarbon. The reaction is allowed to proceed by heating and stirring.

Safety Information:

1. Irritating to skin and eyes: CPS can cause irritation in contact with skin and eyes. If exposed to CPS, flush the area immediately with plenty of water and seek medical help as soon as possible.

2. avoid inhalation and intake: avoid inhalation of CPS dust and intake of CPS. Appropriate respirators and protective gloves should be worn during operation.

3. Storage and handling: CPS should be stored in a cool, dry place, away from fire and flammable materials. Proper laboratory safety practices should be followed when handling CPS.
