Vinyl acetate, MilliporeSigma™ Supelco™
Vinyl acetate is an important ester of vinyl alcohol, which can find applications in the production of homo and copolymer dispersions. The production of vinyl acetate involves the addition of acetic acid to acetylene in the gas phase in the presence of zinc acetate/charcoal as catalyst.
4-Chloro-3-methylphenol, MilliporeSigma™ Supelco™
4-Chloro-3-methylphenol is a biocide, which is colorless crystalline compound. It can be commonly used as a preservative in pharmaceutical products and as an additive to building materials and metal-working fluids.
Brilliant Black BN, ≥95% (HPLC), MilliporeSigma™ Supelco™
Brilliant Black BN (BB) is a azo dye which is basically a tetra sodium salt. It is a synthetic dye mainly used as food additive. It is used as colouring agent to enhance the appearance. It is usually used in jellies, brown sauces and cake mixes.
