Description

3-Trimethylsiloxypropanol is a versatile organosilicon compound, also known as 3-(Trimethylsilyloxy)-1-propanol. This chemical serves as a valuable intermediate and functional additive, prized for its ability to impart hydrophobicity and modify surface properties. It is essential for manufacturers in the pharmaceutical, personal care, and specialty chemical sectors seeking to enhance product performance and stability.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where its silyl group acts as a protecting group for alcohols.
• Personal Care & Cosmetics: Functions as a conditioning agent, emollient, and volatility suppressant in hair care products, skin creams, and antiperspirants.
• Surface Modification Agent: Applied to treat glass, silica, and other oxides to create hydrophobic surfaces or improve adhesion in coatings and composites.
• Polymer & Resin Modification: Acts as a crosslinking agent or chain transfer agent in silicone and organic polymer synthesis.
• Lubricant & Release Agent: Used as an additive in specialty lubricants and mold release formulations for plastics and rubber.
• Chemical Synthesis Reagent: Serves as a reagent for introducing the trimethylsiloxypropyl moiety into more complex organic molecules.

Quality Control

Our 3-Trimethylsiloxypropanol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including GC and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed after opening to minimize moisture uptake and evaporation. Keep away from strong acids and bases.
