  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. What is the molarity of this 90% nitric acid, Product 258121?

    Using the density of 1.50 g/mL and the molecular weight of 63.01 g/mol, we can convert the 90% (wt/wt) to a molarity of about 21.4 M.

  4. What is the difference between Product 258121 and the 90% red, fuming nitric acid (Product No. 309079)?

    Product 258121 is a colorless to yellow solution of nitric acid that has at least 90% as HNO3 and less than 0.1% dissolved oxides. Product 309079 appears red because it can contain 5-10% of dissolved nitrogen oxide (as N2O3 ).

  5. What is the pH of Nitric acid,  Product 258121?

    As a 1% solution in water, 90% nitric acid is expected to have a pH that is less than 1.

Microchemical analysis of otolith (calcified 'ear stones' used for balance and orientation) of fishes is an important tool for studying their environmental history and management. However, the spatial resolution achieved is often too coarse to examine short-term events occurring in

Uncontrolled reactions in biological media are a main obstacle for clinical translation of V-based anti-diabetic or anti-cancer pro-drugs. We investigated the use of controlled-release pharmaceutical formulations to ameliorate this issue with a series of V(V) and (IV) complexes of anionic
