We have a static QA&QC system and all products are in line with the USP32 standard as well as enterprise internal control standard.

Our QC department will do sampling and carry out strict tests through HPLC and GC.

Only when the product is passed through the strict test, they are allowed to be dispatched out.

And our company has been manufacturing Beta-Bromostyrene for years with high reputation.

The fragrance of this product is not the top grade, so the high-grade flavor is not used, but because of its moderate price, it is often used as a soap flavor.

Application:

β-Bromostyrene was used in the one-pot method for the preparation of cinnamonitriles.

It was also used in the preparation of pure ethyl Z- and E-α, α-difluoro-4-phenyl-3-bu tenoate and 1, 3-diphenyl-1-butene.

It may be used in the synthesis of β-tert-butylstyrene via cross coupling reaction with tert-butylmagnesium chloride in the presence of dichloro[1, 1′-bis(diphenylphosphin o)ferrocene]nickel(II) catalyst.

It may also be used to prepare γ-but-2-enolactone by reacting with nickel carbonyl in the presence of alkynes.
