Stability Light Sensitive Applications 3-Acetylpyrrole is a useful research reagent for organic synthesis and other chemical and pharmaceutical processes. References He, Y., et al.: Organic Lett., 13, 4490 (2011); Santos, A. F. L. O. M., et al.: J. Phys. Chem. A., 113, 3630 (2009)

2-Chloro-5-methylpyrimidine (2CMP) is a medicinal chemical that belongs to the class of organic solvents. It is used in the synthesis of homologues and as a dehydrogenation agent for the production of chiral products. 2CMP can be used for large-scale syntheses because it has a high boiling point, low toxicity, and low cost. 2CMP is also used as a reagent in organic chemistry reactions, such as hydroxylations, esterifications, and oxidations. The use of 2CMP as a reagent leads to stereospecific reactions with high yields. 2CMP can be used as an alternative to other dehydrogenation agents such as sodium borohydride or hydrogen gas because it does not produce reactive intermediates that are hazardous to health or environment.

1-(3-Nitrophenyl)piperazine is a nitro substituted piperazine that has been shown to interact with the 5-HT receptor subtype. The protonation of the molecule at physiological pH results in an enhancement of binding to the 5-HT receptor and subsequent downstream effects, such as biphenyl inhibition of programmed cell death. This compound also has been shown to be a ligand for the death receptor chalcone. 1-(3-Nitrophenyl)piperazine binds to the death ligand site on chalcone and inhibits cellular proliferation in vitro.

2-Methylthio-4-hydroxypyrimidine is a protonated thione that inhibits the growth of bacteria, including Streptococcus faecalis.
