1,1,1,3,5,5,5-Heptamethyltrisiloxane CAS No:1873-88-7 C7H22O2Si3

Main Applications

1.‌Synthesis Intermediates‌: Contains active silicon-hydrogen (Si-H) bonds and serves as a basic raw material for the preparation of polyether-modified trisiloxanes.

2.‌Additive Applications‌: Its derivatives are widely used as‌ pesticide spray adjuvants‌ (significantly reducing surface tension and improving spread and coverage) and‌ coating leveling/wetting agents‌.

3.‌Other Applications‌: Some are used as intermediates for silicone modification and the synthesis of specific pharmaceuticals.‌‌

Storage and Precautions

1.‌Environmental Requirements‌: Store in a cool (recommended <25°C), dry, and well-ventilated warehouse. Keep containers tightly sealed and avoid direct sunlight.

2.‌Safety Precautions‌: This product is a flammable liquid (flash point approximately 22–53°C) and must be kept away from open flames, high heat, and strong oxidizing agents; locked storage is recommended, and it must be stored and transported separately from food ingredients.
