2-Bromo-2-nitro-1,3-propanediol (BNP) is a preservative that is used in wastewater treatment. It is an antimicrobial agent that has synergistic effects with other antimicrobial agents such as triclosan, benzalkonium chloride and sesquiterpene lactones. 2-Bromo-2-nitro-1,3-propanediol has been shown to have a phase transition temperature of -28°C, which can be used to identify it in the laboratory. This compound also has a pK value of 4.4, which indicates that it is weakly acidic. 2-Bromo-2-nitro-1,3-propanediol can be used as an analytical method for the determination of p - hydroxybenzoic acid in aqueous samples by electrochemical impedance spectroscopy (EIS).

DL-Tartaric acid is a calcium salt of tartaric acid. It is used as a standard in the analysis of total calcium and tartaric acid content in beverages, wines, foodstuffs, and pharmaceuticals. DL-Tartaric acid can be used to prepare standard solutions for the determination of benzalkonium chloride and other natural compounds by chromatographic methods. The rate constants for the reaction between DL-tartaric acid and calcium pantothenate have been determined by electrochemical impedance spectroscopy. The fluorescence intensity of chemiluminescent reactions with DL-tartaric acid has been found to be proportional to the concentration of tartrate ions in solution. X-ray diffraction data confirm that DL-tartaric acid is an orthorhombic crystal system with space group P2/c.

2-(4-Chlorophenoxy)ethanol is a fatty acid that has shown antimicrobial activity against a number of bacteria and fungi. 2-(4-Chlorophenoxy)ethanol is active against the protozoan Trichomonas vaginalis and has been used in the treatment of bacterial vaginosis. The mechanism of action for the antimicrobial activity of 2-(4-Chlorophenoxy)ethanol is unknown, but it may be due to interference with lipid metabolism or by producing reactive oxygen species and damaging cellular membranes. This compound also possesses anti-inflammatory properties and has been shown to inhibit tumor necrosis factor-α (TNF-α) production in human monocytes.

2-Oxa-6-azaspiro[3.4]octane is an epidermal growth factor (EGF) inhibitor that has shown inhibitory activities against a number of different EGFR-related cell lines, including parental and mutant cell lines. This drug has been shown to inhibit the proliferation of cancer cells in vitro by binding to the epidermal growth receptor (EGFR). 2-Oxa-6-azaspiro[3.4]octane also inhibits the activity of tyrosine kinases and factor receptors, which are involved in the development of cancer cells. It is a potent inhibitor of TK1 and TK2 tyrosine kinases, and is more potent than piperazine or morpholine, which are other EGF inhibitors.
