General description

Benzene is a monocyclic aromatic compound used as a solvent in chemical reactions. It is an essential raw material for fuels, rubber and plastics products, detergents, pesticides, and pharmaceuticals.
Our premium ACS solvents are ideal for routine chemical synthesis, drying, purification, and critical labware cleaning. They meet or exceed the rigorous standards of the American Chemical Society (ACS), ensuring high-quality results for your research needs.

Premium ACS Solvents: Our solvents meet or exceed the stringent standards set by the American Chemical Society, ensuring high quality and reliability for your laboratory applications.

Replicable and Publishable Results: Designed for consistency, our solvents deliver results that can be reliably reproduced, making them ideal for research that requires publication.

Versatile Applications: Suitable for routine chemical synthesis, drying, purification, and critical labware cleaning, our solvents cater to a wide range of research needs in the laboratory.

Application

Benzene can be used as a solvent in the:
  • Heck Reaction of vinyl bromides with styrenes to synthesize functionalized 1,3-dienes.
  • Gallium-catalyzed reductive lactonization of γ-keto acids to γ-lactone derivatives.
  • Anionic polymerization of styrene and 1,3-butadiene in the presence of phosphazene as a base.

Benzene causes acute myeloid leukemia and probably other hematological malignancies. As benzene also causes hematotoxicity even in workers exposed to levels below the US permissible occupational exposure limit of 1 part per million, further assessment of the health risks associated

The use of occupational cohort studies to assess the association of benzene and lymphoma is complicated by problems with exposure misclassification, outcome classification, and low statistical power. We performed meta-analyses of occupational cohort studies for five different lymphoma categories: Hodgkin

Benzene exposure has been associated with increased risk of leukaemia and myelodysplastic syndrome. Existing studies are sparse for other lymphohaematopoietic cancer subtypes, such as myeloproliferative disease (MPD) and the related chronic myeloid leukaemia (CML).
