Product Overview

Ascorbic acid, also known as vitamin C, is an essential water-soluble vitamin, that appears as a white or colorless crystalline powder. This compound, with the ascorbic acid chemical formula C6H8O6, is soluble in water and ethanol, although its solubility decreases at higher temperatures. The ascorbic acid molar mass is 176.12 g/mol, contributing to its specific chemical properties. It has a density of 1.65g/cm^3 and is notably sensitive to oxygen and light, particularly when in solution. As a hygroscopic substance, ascorbic acid powder requires careful storage to prevent caking and maintain its integrity.
