What is the Cotinine?
The molecule Cotinine presents a molecular formula of C10H12N2O and its IUPAC name is (5S)-1-methyl-5-pyridin-3-ylpyrrolidin-2-one.
Cotinine is a molecule that is produced when the body metabolizes nicotine, a chemical found in tobacco products such as cigarettes, cigars, and chewing tobacco. Cotinine is present in the blood, urine, and saliva of individuals who use tobacco products, and its levels can be used to determine an individual's tobacco use or exposure to secondhand smoke..
Cotinine is classified as a nicotinic agonist, meaning that it activates the same receptors in the brain as nicotine does. Like nicotine, cotinine can have stimulant effects on the central nervous system, including increased heart rate, blood pressure, and alertness. It can also increase the risk of cardiovascular disease, stroke, and other health problems associated with tobacco use..
Cotinine is often used as a biomarker to measure tobacco use or exposure to secondhand smoke. It is typically detected through a blood or urine test, and the results are used to help individuals quit smoking or to monitor their progress in quitting. Cotinine levels can also be used to help identify individuals who may be at increased risk for tobacco-related health problems..
In summary, cotinine is a molecule produced when the body metabolizes nicotine, a chemical found in tobacco products. It is often used as a biomarker to measure tobacco use or exposure to secondhand smoke, and its presence in the body can indicate an increased risk for tobacco-related health problems..

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.

Physico-Chemical properties
| IUPAC name | (5S)-1-methyl-5-pyridin-3-ylpyrrolidin-2-one |
| Molecular formula | C10H12N2O |
| Molecular weight | 176.215 |
| Melting point (ºC) | |
| Boiling point (ºC) | |
| Density (g/cm3) | |
| Molar refractivity | 53.33 |
| LogP | 1.3 |
| Topological polar surface area | 33.2 |
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.
