💡 Commercial Applications
2,6-Dichlorophenoxyacetic acid, commonly known as 2,6-D, is primarily utilized in agriculture as a herbicide to control a wide variety of broadleaf weeds. Its commercial applications extend to lawn care, forestry, and horticulture where it is used to eliminate unwanted vegetation without harming crops or desirable plants.
In the industrial sector, 2,6-D finds use as a growth regulator in plant tissue culture and as a selective agent in genetic engineering. Its ability to induce controlled plant growth and promote callus formation makes it a valuable tool in plant biotechnology research and development.
While 2,6-D is primarily known for its herbicidal properties, it also has pharmaceutical applications. In medicine, it is used to treat hormonal disorders such as hyperthyroidism by suppressing the overproduction of thyroid hormones. Additionally, 2,6-D has been investigated for its potential in cancer treatment due to its ability to induce cell death in certain tumor cells.
⚗️ Chemical & Physical Properties
2,6-Dichlorophenoxyacetic acid is a white crystalline solid with a faint odor. It is sparingly soluble in water and has a strong acidic taste. The odor of the chemical is often described as weak and not very distinct.
With a molar mass of 221.03 g/mol and a density of 1.641 g/cm³, 2,6-Dichlorophenoxyacetic acid is heavier and denser than common food items such as sugar (molar mass: 342.3 g/mol, density: 1.59 g/cm³) and salt (molar mass: 58.44 g/mol, density: 2.16 g/cm³). The chemical’s molar mass and density contribute to its physical properties and behavior in various environments.
The melting point of 2,6-Dichlorophenoxyacetic acid is approximately 142-143°C, while its boiling point is around 160-161°C. In comparison, common food items like butter (melting point: 32-35°C, boiling point: 177°C) and olive oil (melting point: -6°C, boiling point: 297°C) have significantly lower melting and boiling points. These differences in physical properties are important in understanding how the chemical behaves under different conditions.
2,6-Dichlorophenoxyacetic acid is moderately soluble in water and has a high viscosity. Compared to common food items like vinegar (soluble in water, low viscosity) and honey (insoluble in water, high viscosity), the chemical exhibits different solubility and viscosity characteristics. These properties affect its interactions with other substances and its ability to dissolve or mix in various solutions.
