This product is soluble in dimethylformamide (DMF, 50 mg/mL), with heat as needed, yielding a clear, yellow/green solution. It is also soluble in water (0.19 mg/mL), ethanol (0.51 mg/mL), acetone (5.1 mg/mL), glycerol (0.6 mg/mL), and polyethylene glycol (15 mg/mL). Nitrofurantoin is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, dissolve first in DMSO and then dilute with the buffer of choice. It has a solubility of ~0.5 mg/mL in a 1:2 solution of DMSO:PBS (pH 7.2) using this method. It is not recommended to store the aqueous solution for longer than a day.

Application
Nitrofurantoin is a nitrofuran antibiotic that is used as a substrate of bacterial nitrofuran reductase to study the interactions of active metabolites with DNA, ribosomal proteins and metabolic and pro-oxidant processes. It is used to study nitrofurantoin-induced toxicity and antibiotic resistance.Nitrofurantoin is suitable for killing L. monocytogenes-persisters in vitro. Studies has described the use of antioxidants to mitigate the toxic effects of nitrofurantoin on human WI-38 fibroblasts in culture. Alterations to the in vitro morphologic features, viability, and phagocytic activity of isolated bovine mammary polymorphonuclear leukocytes caused by various antibiotics, including nitrofurantoin, have been reported.
Biochem/physiol Actions
Nitrofurantoin is an antibactericidal compound that has been historically prepared by the reaction of 1-aminohydantoin sulfate and 5-nitro-2-furaldehyde diacetate. It shows activity against many Gram-positive and Gram-negative bacteria. Nitrofurantoin is effective against enterococci, staphylococci, streptococci, corneybacteria, many strains of Escherichia coli. Most strains of Proteus spp. and Pseudomonas aeurginosa are more resistant to this compound. Nitrofurantoin is activated by bacterial flavoproteins (nitrofuran reductase) to actively reduce reactive intermediates that modulate and damage ribosomal proteins or other macromolecules, such as DNA. This inhibits DNA, RNA, protein, and cell wall synthesis which causes cell death. Nitrofurantoin has a low resistance potential that is rapidly metabolized by mammals and is active against both Gram-positive and Gram-negative bacteria. It is also a pro-oxidant that is cytotoxic due to the generation of intracellular H 2O2. It is an inhibitor of glutathione reductase. Nitrofurantoin produces hepatotoxicity caused by the redox cycling of the nitro group and its radical anion which leads to oxidative stress.
Other Notes

I purchased Nitrofurantoin (N7878). It dissolves in DMSO, but precipitates immediately when water or medium is added, even below 1–3% DMSO. What is the recommended solvent and how can I prepare a stable stock solution?”

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
