What is the M-Nitrobenzaldehyde?
The molecule M-Nitrobenzaldehyde presents a molecular formula of C7H5NO3 and its IUPAC name is m-nitrobenzaldehyde.
M-Nitrobenzaldehyde is an organic molecule consisting of a benzene ring with a nitro group attached to the meta (middle) position. It is a pale yellow solid that is insoluble in water and has a strong, unpleasant odor. It is used as a reagent in organic synthesis and as a starting material for the production of dyes and pigments..
M-Nitrobenzaldehyde is produced by the nitration of benzaldehyde. The nitration of benzaldehyde can be achieved by treating the molecule with a mixture of nitric and sulfuric acids. The resulting product is a mixture of ortho- and para-nitrobenzaldehydes, which can be separated by column chromatography..
M-Nitrobenzaldehyde is a versatile molecule that can be used in a variety of synthetic reactions. It is commonly used as a nucleophile in substitution reactions and as a electrophile in addition reactions. It can also be used in condensation reactions to form heterocycles..
The reactivity of M-nitrobenzaldehyde can be attributed to the presence of the nitro group. The nitro group is a strong electron-withdrawing group, which makes the benzene ring more susceptible to attack by nucleophiles and electrophiles. The presence of the nitro group also makes M-nitrobenzaldehyde more reactive than benzaldehyde..
M-Nitrobenzaldehyde is a dangerous substance and should be handled with care. It is highly flammable and can explode if heated. It is also corrosive and can cause burns to the skin and eyes..

Other names (synonyms)
IUPAC nomenclature provides a standardized method for naming chemical compounds. Although this system is widely used in chemistry, many chemical compounds have also other names commonly used in different contexts. These synonyms can come from a variety of sources and are used for a variety of purposes.
One common source of synonyms for chemical compounds is the common or trivial names, assigned on the basis of appearance, properties, or origin of the molecule.
Another source of synonyms are historical or obsolete names employed in the past, however replaced nowadays by more modern or standardized names.
In addition to common and historical names, chemical compounds may also have synonyms that are specific to a particular field or industry.

LogP and topological polar surface area (TPSA) values were estimated using Open Babel software.
The n-octanol/water partition coeficient (Kow) data is applied in toxicology and drug research. Kow values are used, to guess the environmental fate of persistent organic pollutants. High partition coefficients values, tend to accumulate in the fatty tissue of organisms. Molecules with a log(Kow) (or LogP) greater than 5 are considered to bioaccumulate.
TPSA values are the sum of the surface area over all polar atoms or molecules, mainly oxygen and nitrogen, also including hydrogen atoms.
In medicinal chemistry, TPSA is used to assess the ability of a drug to permeabilise cells.
For molecules to penetrate the blood-brain barrier (and act on receptors in the central nervous system), TPSA values below 90 Å2 are required. Thus, molecules with a polar surface area greater than 140 Å2 tend to be poorly permeable to cell membranes.
