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

一般描述
应用
- 作为染料用于旋涂法制作酚红/n-Si光二极管[酚红/n型硅片]。该器件适合光电检测应用。
- 作为变色染料，用于设计光纤pH传感器，因为随着酸度的升高，染料的吸收峰会从光谱的绿色部分移动到蓝色部分。
- 作为测量淡水pH值时的指示剂。
特点和优势
- pH 6.4及以下显黄色
- pH 8.2及以上显红色。
分析说明
第1个转变范围：pH 1.2 - pH 3.0 棕橙色-黄色
第2个转变范围：pH 6.5 - pH 8.0 棕黄色-红紫色
干燥失重（110 °C）： ≤ 1
转换范围（根据ACS）：通过测试

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.
