⚗️ Chemical & Physical Properties
3,3′-Thiodipropionic acid appears as a white crystalline powder with a slight sulfur-like odor when in pure form. The compound is highly hygroscopic and readily absorbs moisture from the air, causing clumping and loss of free-flowing characteristics.
With a molar mass of approximately 202.27 g/mol and a density of about 1.27 g/cm³, 3,3′-Thiodipropionic acid is heavier than many common food items such as sugar and salt. This higher molar mass and density contribute to its solid, crystalline nature and distinguish it from lighter food substances.
3,3′-Thiodipropionic acid has a melting point of around 87-89°C and a boiling point of approximately 208-210°C. These values are significantly higher than those of many food items, such as butter and olive oil, which have lower melting and boiling points. The compound’s higher melting and boiling points reflect its increased stability and resistance to temperature changes.
This compound has limited solubility in water and forms a viscous solution when dissolved. Its solubility is lower compared to many food items, like sugar and salt, which readily dissolve in water. The higher viscosity of 3,3′-Thiodipropionic acid solution distinguishes it from the more fluid consistency of common food items dissolved in water.
