Certificado de análise

Certificado de origem

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Does Product 156159, Sodium Cyanoborohydride, typically have an odor?

    Sodium cyanoborohydride may have an unusual odor due to production steps. It is our belief that this odor is the result of trace amounts of volatile organosulfur compounds which are present as a result of a new manufacturing process.  While this odor may be unpleasant, we are confident the impurity is present at such a low level that it will not affect the performance of this reagent for most applications. If the odor persists in the waste streams following use of this reagent, it can be removed by treating these mixtures with aqueous bleach. In regards to the hazards of the volatile organosulfur compounds, these compounds have a very strong odor which would cause you to remove yourself from the compound's presence much sooner than you would begin to suffer affects from toxicity of these compounds; however, this is research grade material and you should be handling it properly (according to MSDS). The sodium cyanoborohydride itself is a bigger safety concern than the small amounts of organosulfur impurities present in this product.

  4. What impurities are present in Product 156159, Sodium Cyanoborohydride?

    One of the by-products of the synthesis reaction is Dimethyl Sulfide.  It is also possible that there could be some Borate salts present. 

  5. Why is it recommended to store and handle Product 156159, Sodium Cyanoborohydride, under an inert atmosphere?

    Sodium Cyanoborohydride is a very hygroscopic material and contact with water or moist air should be avoided.  Allowing the material to come into contact with water or moist air may decompose the material and could lead to a violent reaction or explosion due to the release of Hydrogen gas. 

  6. What is Product 156159, Sodium Cyanoborohydride, soluble in?

    According to the chemicals encyclopedia published by the Royal Society of Chemistry, 13th Edition, Sodium Cyanoborohydride is soluble in water (212g / 100g solvent), Tetrhydrofuran (37.2g / 100g solvent), and Diglyme (17.6g / 100g solvent).  It is also very soluble in Methanol, slightly soluble in Ethanol and Isopropylamine, and insoluble in Ethyl Ether, Benzene, and Hexane.

Glycan Labeling

Structural modifications of proteins are essential to living cells. When aberrantly regulated they are often the basis of disease. Glycans are responsible for much of the structural variation in biologic systems, and their representation on cell surfaces is commonly called the “glycome.”
