  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. What is the apparent molarity of Citral, Products W230316, C83007, and W230308?

    The apparent molarity of a neat liquid may be calculated from the density and molecular weight.  In the case of citral, the density is 0.888 g/mL and the molecular weight is 152.23 g/mole. By writing the density as 888 g/L, the calculation is 888 g/L divided by 152.23 g/mole = 5.83 mole/L, or 5.83 M.
