General description
La nicotina es el alcaloide más abundante encontrado en las hojas de las especies del género Nicotiana. Es un agente tóxico importante.
Application
La (-)-nicotina se ha utilizado:
- para estimular los neutrófilos en ensayos de fluorescencia de ADN extracelular y en inmunotinción de neutrófilos
- para estudiar los efectos de la exposición crónica neonatal a la nicotina en la unión al receptor nicotínico de la acetilcolina (nAChR), la muerte celular y la morfología del hipocampo y el cerebelo
- en un estudio in vitro para evaluar el efecto de la exposición radicular a la nicotina o la cotinina en la morfología y densidad de los fibroblastos
Biochem/physiol Actions
Receptor prototipo agonista nicotínico de la acetilcolina; isómero que se encuentra en estado natural.
La nicotina se une a los receptores nicotínicos de acetilcolina y exhibe efectos a la vez neuroprotectores y neurotóxicos en el cerebro en desarrollo. Se asocia con el desarrollo de cáncer de pulmón y reduce la eficiencia de los quimioterápicos. Además, la nicotina tiene capacidad para deteriorar la defensa fagocítica del huésped y también aumenta la lesión asociada a las especies de oxígeno reactivo (ROS). También detiene la desactivación de la Akt/ proteincinasa B (PKB) y reduce la muerte espontánea de los neutrófilos. La nicotina se utiliza para el tratamiento de las enfermedades de Alzheimer y de Parkinson.
Preparation Note
Este producto debe ser disuelto en etanol puro de 200 grados.

Hi , How i want to measure the purity level of nicotine? Can refractive index or polarimeter use to measure level of impurity?
1 answer-
The measurement of purity in nicotine can be assessed using various analytical techniques. Refractive index and polarimetry are among the methods that can provide useful information. However, it's important to note that these techniques may not directly measure specific impurities but can be indicative of changes in the overall composition or characteristics of a substance. The purity of this product is determined by GC. Gas Chromatography (GC) is a widely used and effective method for assessing the purity of nicotine and detecting impurities. GC separates and analyzes components based on their volatility and interaction with a stationary phase.

How long is the nicotine stable if stored at room temperature? How long is it stable after being dssiolved and how should the solution be stored?
1 answer-
This compound is stored at room temperature, but is extremely sensitive to light, moisture, and oxygen. The product is a neat liquid and packaged in amber glass under argon to preserve stability. In the unopened container, the product is stable at least until the recommended retest date reported on the lot specific Certificate of Analysis. This date is typically 3 years from the quality release date. Factors such as light, humidity, and exposure to air will limit the shelf life after opening, It is recommended to prepare solutions fresh. The vial head space should be cleared with argon or nitrogen prior to closing. Increased darkening of the material is an indication of product degradation.

What is the molarity of Product N3876, (-)-Nicotine?
1 answer-
The molarity of (-)-Nicotine is 6.23 M based on a 100% pure compound with a density at 20 °C equal to 1.010 g/mL. If you multiply this density by 1000, you obtain g/L. If you divide g/L by the molecular weight of (-)-Nicotine which is 162.2 g/mole, you get moles per L which is molarity. [1.010 x 1000]/162.2 = 6.23 M.
