4-tert-Butylbromobenzene_3972-65-4_High Purity 4-Bromo-tert-butylbenzene_Pharmaceutical Intermediate

Core Product Parameters:

4-tert-Butylbromobenzene (CAS: 3972-65-4), with the molecular formula C10H13Br and a molecular weight of 213.12, is a colorless to pale yellow transparent liquid at room temperature. It is an important para-substituted aromatic halohydrocarbon. Due to the bromine atom and the tert-butyl group being in the para position, it exhibits unique steric hindrance effects and reactivity, making it widely used as a pharmaceutical intermediate and organic synthesis building block.

Specifications and Quality Control:

We offer high-purity 4-tert-Butylbromobenzene with a standard specification of ≥99.0%. Through advanced distillation processes and stringent quality control, our product features low moisture and low impurity levels. Each batch is analyzed by gas chromatography (GC) to ensure stable and reliable quality, meeting diverse needs from laboratory research to industrial production.
