(2-Bromoethoxy)-tert-butyldimethylsilane (BrCH2CH2OTBS) is an alkylating agent used in organic synthesis to attach a TBS-protected 2-hydroxyethyl group to nucleophiles such as phenols, amines and thiols. The silyl ether keeps the hydroxyl masked during later steps and can be removed afterwards to reveal a free 2-hydroxyethyl group. CAS 86864-60-0, molecular formula C8H19BrOSi, molecular weight 239.22. Store at 2–8°C. Signal word: Warning. Molekula supplies (2-Bromoethoxy)-tert-butyldimethylsilane from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
