Product Description:

Saccharin is an artificial sweetener with the chemical formula C7H5NO3S. It is a white, crystalline powder that is approximately 300-500 times sweeter than sucrose but has a bitter or metallic aftertaste, especially at high concentrations. Its core structure is based on benzoic sulfimide. Its primary and most significant application is as a non-nutritive sweetener in a wide range of food and beverage products, including soft drinks, tabletop sweeteners, baked goods, and canned foods. It is valued for its stability under heat and over a wide pH range, and it does not contribute to calories or raise blood sugar levels, making it suitable for diabetic diets and weight management products. It is often used in combination with other sweeteners to mask its aftertaste. Beyond its role as a food additive, saccharin and its salts (e.g., sodium saccharin) are also used in cosmetic products, pharmaceuticals (e.g., chewable tablets), and electroplating baths. As an organic synthetic building block containing imide and sulfonamide functional groups, it finds niche applications in chemical synthesis and coordination chemistry.
