  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 Product 452483, 1-Methyl-D-tryptophan, soluble in?

    While we don't test the solubility of this product directly, we do have to dissolve it in acetic acid in order to test the optical rotation. We would also expect this to be soluble in a dilute hydrochloric acid solution (50mg/mL in 5N HCl). Both heat and sonication may be required in order to prepare a homogenous solution. Also, based on our experience with the DL (Product No. 860646) and L (Product No. 447439) forms, we would expect that dilute sodium hydroxide would also be a potential solvent (1g/100mL of 1M NaOH).

  4. What is the solution stability of Product 452483, 1-Methyl-D-tryptophan?

    Unfortunately, we do not perform solution stability testing on this item or have experience with storing tryptophan solutions, so we would recommend making a fresh batch with each use.

  5. How should Product 452483, 1-Methyl-D-tryptophan, be stored?

    This material is stable at room temperature without any special handling precautions.
