分析证书(COA)
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. See Shipping and Storage for more information.
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.
How do I get lot-specific information or a Certificate of Analysis?

Is (-)-Epigallocatechin gallate (Product No. E4143) sterile and tested for endotoxins?
Product No. E4143 ((-)-Epigallocatechin gallate) is not prepared under sterile conditions and has not been tested for endotoxins.
Is (-)-Epigallocatechin gallate (Product No. E4143) for human use
No. Product No. E4143 ((-)-Epigallocatechin gallate) is for laboratory research use only, not for human use.
What is the solubility of (-)-Epigallocatechin gallate (E4143)?
We have tested the solubility of (-)-Epigallocatechin gallate at 5 mg/mL in water.
What is the solution stability of (-)-Epigallocatechin gallate (E4143)?
A solution of (-)-Epigallocatechin gallate in water at a concentration of 0.3 mg/mL was found to have significantly decreased in purity (from 99.6% to 81.7%) after 2.5 hours at room temperature. A similar solution of (-)-Epigallocatechin gallate in water at a concentration of 0.3 mg/mL was found to have decreased in purity only slightly (from 99.5% to 99.3%) after 2.0 hours at 4°C.
Can (-)-Epigallocatechin gallate be determined in plasma and urine?
The determination of (-)-Epigallocatechin gallate in plasma and urine by HPLC has been reported in Cancer Epidemiol. Biomark. Prev., 4, 393 (1995).
