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

Usage: Thick aroma of thick thorns and powerful astringent, sweet cream with
fragrant leaves diluted with hyacinth and aroma, the aroma does not stay long. A
representative product of a halogenated hydrocarbon perfume, which is not
naturally present, is artificially synthesized. Also used lilac, narcissus,
daffodil, sunflower, sweet curry, Hong Wei and other flavor in the.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.
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-butenoate 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(diphenylphosphino)ferrocen , e]nickel(II) catalyst.It may also be used to prepare
γ-but-2-enolactone by reacting with nickel carbonyl in the presence of alkynes.
