Organic Reagents

There are over 700 products specifically categorised as organic reagents in the portfolio. Sub-sets of products are taken from all aspects of organic chemistry including reagents used for halogenation, oxidation and reduction. Products are as diverse as relatively simple molecules like acetic anhydride to complex molecules such as EDTA, all with specific functional reagent capabilities to facilitate transformations. Where beneficial, products are available as pre-made solutions, e.g. Glutaraldehyde (both 50% and 25% aqueous solution), Sodium biphenyl in diethylene glycol diethyl ether, (Trimethylsilyl)diazomethane in hexanes, Sodium methoxide in methanol and Borane-tetrahydrofuran complex in THF, alongside high purity products such as Imidazole, Phenol, Sodium borohydride and N-Bromosuccinimide.

Reagents in AcroSeal Packaging

When carrying out synthetic organic chemistry, exposing many solvents and reagents to air and moisture inhibits their ability to perform properly and can cause some, if not all, of the following issues:

  • A failed synthesis
  • Poor yield
  • Greater number of by-products/impurities
  • More challenging purification

Our AcroSeal packaging solution is innovative and simple as we endeavour to:-

  • Pack the product when it is as dry as possible
  • Make it easy to keep it dry when transferring from the packaging into your dry system
  • Ensure products stay dry between repeated use

As well as the challenge of keeping air and mositure out of the reaction system, the highly reactive reagents often required in organic synthesis may be hazardous to use, including compounds that can be pyrophoric, toxic, carcinogenic, mutagenic, corrosive and odourous e.g. thiols. AcroSeal packaging also provides a safer solution for handling these reagents by allowing removal of the reagent from the bottle under an inert atmosphere and without exposure to the contents.
