Description

1,3,5,7,9,11,14-Heptacyclopentyltricyclo[7.3.3.1(5,11)]Heptasiloxane-Endo-3,7,14-Triol is a highly functionalized, cage-structured organosilicon compound, also known as a polyhedral oligomeric silsesquioxane (POSS) derivative. This advanced material is valued for its ability to act as a nanoscale reinforcing agent and a versatile chemical building block, imparting enhanced thermal stability, mechanical strength, and unique surface properties to composite materials. It is primarily sought by R&D and production teams in the advanced polymers, specialty coatings, and high-performance materials sectors.

Application

• Advanced Polymer Composites: As a nanofiller to enhance thermal stability, mechanical strength (modulus), and flame retardancy in engineering plastics, silicones, and epoxies.
• Specialty Coatings & Films: To improve scratch resistance, thermal insulation, and dielectric properties in protective and electronic coatings.
• Hybrid Material Synthesis: As a precise molecular scaffold or precursor for creating organic-inorganic hybrid materials with tailored properties.
• Adhesives & Sealants: To modify rheology and increase the heat resistance and durability of high-performance formulations.
• Electronics & Optoelectronics: As a component in low-k dielectric materials, encapsulants, or as a platform for sensor development.
• Catalyst & Ligand Support: Utilizing its robust, three-dimensional structure to support catalytic species or create well-defined catalytic sites.
• Personal Care & Cosmetics: Potential use as a texturizing or film-forming agent in premium formulations.

Quality Control

Our production of 1,3,5,7,9,11,14-Heptacyclopentyltricyclo[7.3.3.1(5,11)]Heptasiloxane-Endo-3,7,14-Triol adheres to a strict quality management system. Each batch undergoes comprehensive analytical testing, including NMR, FT-IR, and HPLC, to verify chemical structure, purity, and consistency. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment to ensure full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under dry, inert conditions (e.g., nitrogen atmosphere) at a controlled room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and potential degradation.
