If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
If we assume an H2O2 concentration of 30% (w/w) and a density of 1.11 g/mL, then the approximate molarity is 9.8 M. You may use the exact concentration of the lot to calculate molarity more precisely. This product is 29.0% to 32.0 % (w/w).
You can use the molar extinction coefficient of H2O2, which is 43.6 M-1cm-1at 240 nm. Using the Beer-Lambert Law, A = ebc where e = the molar extinction coefficient, b = the path length of the cuvette in cm, and c = molar concentration, you can solve for "c" based on the absorbance you get for a H2O2 solution. If you dilute your solution with a solvent to get an absorbance reading within the capabilities of your spectrophotometer, include the dilution factor in your calculations, and correct your absorbance reading with any absorbance reading contributed by the solvent itself.
According to US Department of Transportation (DOT) regulations, concentrated hydrogen peroxide must be shipped in bottles with vented caps. This is because H2O2 disproportionates to H2O and O2 which can cause pressure buildup. Because the bottles have vented caps, we cannot guarantee that there will be no leakage. The only way to obtain hydrogen peroxide with a sealed cap is to purchase the 3% solution (e.g., Product No. 323381).
