Frequently Asked Questions

How does the storage temperature relate to shipping conditions?
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. http://www.sigmaaldrich.com/etc/medialib/docs/Sigma-Aldrich/General_Information/shippingandlong-termstoragev3.Par.0001.File.tmp/shippingandlong-termstoragev3.pdf

Ammonium pyrrolidinedithiocarbamate is soluble in water at a concentration of approximately 50 mg/mL.
What is the solution stability of Product P8765, Ammonium pyrrolidinedithiocarbamate?
Sigma-Aldrich has not performed a controlled solution stability test on PDTC. However, we have found that aqueous stock solutions are typically stable for at least one month when stored at -20 °C.
What are the difference among the Ammonium pyrrolidinedithiocarbamate Products P8765, 09935, 71935?
Both products P8765 (Sigma brand) and 09935 (Fluka brand) are the same chemical compound but have different specifications. The specification for P8765 is found in the link: http://www.sigmaaldrich.com/catalog/DataSheetPage.do?brandKey=SIGMA&symbol=P8765. For product 09935, the specifications at our website are in the link below: http://www.sigmaaldrich.com/catalog/ProductDetail.do?lang=en&N4=09935|FLUKA&N5=SEARCH_CONCAT_PNO|BRAND_KEY&F=SPEC. Product 71935 is the sodium salt, not the ammonium salt of pyrrolidinedithiocarbamate.
What are some functions reported for Product P8765, Ammonium pyrrolidinedithiocarbamate?
PDTC has been reported to repress vascular cell adhesion molecule-1 (VCAM-1) activation by Interleukin-1β in cultured human umbilical vein endothelial calls. Marui, M., et al., J. Clin. Invest, 92, 1866 (1993).  It inhibits the induction of nitric oxide synthase activity in rat alveolar macrophages. Sherman, M.P., et al., Biochem. Biophys. Res. Commun. 191, 1301-1308 (1993).  It is an Inhibitor of nuclear factor kappa B., Eberhardt, et al. Biochem. Biophys. Res. Commun. 200, 163 (1994). PDTC at 100  µM, totally inhibited the NF-kappa B response in intact cells. Schreck, R., et al., J. Exp. Med. 175 , 1181-1194 (1992). It activates cAMP-dependent protein kinase (PKA) in a colorectal cancer cell line. Chinery, R., et al., J. Biol. Chem., 272, 30356 - 30361, (1997).
