Application

1-Thioglycerol, a derivatization reagent, is used to study the pH-sensitive photoluminescence of aqueous thiol-capped CdTe nanocrystals. 1-Thioglycerol is used to develop and test thiol-functionalized copolymers. 1-Thioglycerol is used as a post-modification agent in the generation of non-standard peptide foldamers.Potential substitute for 2-mercaptoethanol; probe for the study of lymphocyte activation[1].

Preparation Note

This product is miscible in ethanol (1 ml/ml, 50%, v/v), yielding a clear, colorless solution. It is also miscible in water (0.1 M).

Questions

1–3 of 3 Questions  
  1. What is the concentration of the 1-thioglycerol?

    1 answer
    1. The liquid is not a solution of 1-thioglycerol in some solvent. Rather, it is a neat liquid (i.e., essentially pure 1-thioglycerol). Based on a density of 1.245 g/mL and a molecular weight of 108.2 g/mole, one can calculate an effective molarity of 11.5 M. This information may be found on the M1753 product information sheet.

  3. How does the storage temperature relate to shipping conditions?

    1 answer
    1. The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
