If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

We need to verify a purity of this reagent. We only have HPLC available. Can you please suggest an appropriate method for TMPTA detection?
1 answer-
Unfortunately, this product is tested for purity by GC and has never been tested by HPLC. A brief search of the literature reveals that ECHA (European Chemicals Agency) publishes the HPLC conditions in the CLH report for TMPTA.
See the link below, page 75, to review columns and conditions:

구성성분 함량에 대해 질문드립니다. COA상에 순도가 77.2 % 로 되어 있습니다. 22.8 % 의 물질은 무엇으로 구성되어 있는지 확인을 요청드립니다. 저희는 화학물질 등록시 귀사에서 물질을 사서 시험하여 등록을 진행하였으나, 주무당국으로 부터 물질의 순도에 대한 증빙자료를 보완요청 받았습니다. 즉 순도가 77.2 %인데, 그럼 22.8 % 의 물질은 무엇인가에 대한 자료를 소명해야하여 이와같은 요청을 드립니다. 감사합니다.
1 answer-
This product has a minimum purity of 70% and is classified as a 'technical grade'. While it does contain a preservative at a very low concentration, no further testing is performed to identify or quantify the impurities.
