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

製薬会社で医薬品の品質試験を行なっている者です。この無水トリフルオロ酢酸の物性として、bp（boiling point：沸点？）がありますが、これは日局などの公定書に基づいて試験実施されておりますでしょうか。可能であれば、試験法の詳細をご教示いただきたいです。ご回答お願いいたします。
1 answer-
As listed in the properties section of the product page, the boiling point for this material is 39.5-40 °C. The physical properties are reported from cited in the literature . Neither the testing, nor the processing, is according to the Japanese Pharmacopoeia or other similar agencies. These methods are considered proprietary and may not be shared. The product is intended for research use only.
