General description
Our anhydrous solvents deliver exceptionally low water content, making them the ideal choice for moisture-sensitive laboratory applications. Packaged in the exclusive Sure/Seal™ septum bottle system, they are reliably protected against moisture ingress from first use to last drop. The innovative Sure/Seal™ closure combines an advanced plug-style liner with an airtight elastomer and crimp cap design to ensure consistent product integrity. Three unique liner materials provide optimal chemical compatibility across a broad range of solvents. Sure/Seal™ packaging is proven to maintain anhydrous conditions even after repeated punctures. With more than 70 products across all major solvent families, available in pack sizes from 100 mL to 2 L, the portfolio meets virtually every laboratory need. By choosing ready-to-use anhydrous solvents in Sure/Seal™ packaging, researchers eliminate the need for time-consuming and hazardous in-house solvent drying and distillation - saving time, reducing risk, and improving reproducibility.
Application
Anhydrous solvents in Sure/Seal™ packaging are essential wherever water contamination would compromise experimental results. They are widely used in moisture-sensitive applications such as organic synthesis - including Grignard reactions, organometallic chemistry, and catalysis - as well as in peptide, oligonucleotide, and pharmaceutical synthesis.

I'm using anhydrous acetonitrile that was opened in 2017. microbubbles frequently occur in the internal tubing(Cellenone machine) . Could this be related to storing it for a long period?
1 answer-
Long-term storage of anhydrous acetonitrile may contribute to the occurrence of microbubbles in the internal tubing of the Cellenone machine. Unopened bottles have a recommended retest period of three years. However, no specific long-term data is available regarding the effects of storage in tubing.

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.

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

Hi! By which method is the acetonitrile dried? Is molecular sieve used? Thanks!
1 answer-
Unfortunately, the manufacturing process of this product is proprietary. If necessary, molecular sieves can help to further dry the product before use.

Hey, my name is Mohammad. We tried to develop sensor ro detect heavy metals. And I fond some peaks in the solution when I added acn 99.8% and I want to know if there is heavy metals and which metals?
1 answer-
Unfortunately, this product is not tested for heavy metals. Should this be a critical issue for the specific application, see product 900667. This product is tested for trace metals and may be a better option. See the link below to review a sample Certificate of Analysis:
