General description
Sodium hydroxide solution is a strong alkali. It is utilized in making cellophane, rayon, bleaches, dyes and drugs. It is also employed to abstract hydrogen sulfide from petroleum and to degrade lignin in wood in the paper industry.
Application
Sodium hydroxide solution may be used in the following processes:
- As a dedoping reagent in the synthesis of graphene/polyaniline hybrid material.
- As a solvent in the weight loss study of aluminum by corrosion.4
- Alkaline reagent test for tannins & phenolic compounds.
- Synthesis of single crystalline zinc stannate (Zn2SnO4 and ZnSnO3) nanoparticles.
- Estimation of protein content and α-cellulose content in grain by-products.

415413-18Lの容器のサイズを教えてください。劇物保管庫に納めることが出来るか確認したいです。
1 answer-
Product 415413-18L is packaged in a high-density polyethylene (HDPE) drum. The solution is so corrosive that it would etch glass or corrode metal, but it is compatible with HDPE. The dimensions of the container are roughly 40 cm in height and 30 cm in diameter. For information on proper storage, please see Section 7 of the Safety Data Sheet (SDS) for this product.

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
