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

SDSに保管温度や溶解条件等が見当たらないので教えていただけますでしょうか。また、現在HPLCの標準物質として使用しており、MeOHに溶解後、乾固凍結、使用時に再溶解しています。溶解後の保存についても最適な方法（乾固の有無・温度・期間）を教えてください。
1 answer-
The neat product is to be stored at room temperature. Busulfan is soluble in organic solvents such as DMSO and dimethyl formamide. The solubility of busulfan in these solvents is approximately 16.7 mg/ml. No solution stability studies are performed for this compound but the literature recommends using the prepared solution within 24 hours.
