01 / OVERVIEW
Product overview
A volatile monofunctional chlorosilane that hydrolyzes rapidly in water. It is primarily a trimethylsilyl source and chain terminator, and a feedstock for hexamethyldisiloxane and hexamethyldisilazane.
02 / SPECIFICATION
Typical specification
The values shown are typical reference data, not guaranteed sales specifications. Final limits are defined by the agreed TDS, contract and batch COA.
03 / APPLICATIONS
Applications
Hexamethyldisiloxane (HMDSO/MM)Produced by controlled hydrolysis and condensation; used as an end-blocker and silicone intermediate.
Hexamethyldisilazane (HMDS)Produced by reaction with ammonia for pharmaceutical, semiconductor and surface-treatment uses.
Trimethylsilyl protecting reagentUsed to silylate and protect hydroxyl, carboxyl and other reactive groups in organic synthesis.
Polysiloxane end-blockingFunctions as a chain terminator/end-blocker to control molecular weight and end groups; it is not the principal backbone monomer.
04 / HANDLING
Packaging, storage and transport
Keep the handling system dry and preferably under nitrogen. Avoid inhalation and skin/eye contact. Do not flush spills directly with water; follow the SDS and use a compatible inert absorbent.
Typical packagingAvailable in sample packs, drums or IBCs depending on product compatibility and order quantity.
Sealing requirementsUse a clean, dry and tightly sealed compatible container; nitrogen protection is recommended for moisture-sensitive grades.
Storage conditionsStore in a cool, dry and well-ventilated place away from moisture, heat, ignition sources and incompatible materials.
Transport and shelf lifeTransport classification and shelf life depend on the exact grade and must follow the latest SDS and confirmed order specification.
Actual packaging, shelf life and dangerous-goods classification must follow the exact grade, order and latest SDS.
