What is Saccharin Sodium CAS 128-44-9?

Saccharin Sodium CAS 128-44-9 is the water-soluble sodium salt of saccharin, also known as sodium o-benzosulfimide. Its anhydrous molecular formula is C7H4NNaO3S, with molecular weight about 205.17 and EINECS 204-886-1.

How does Saccharin Sodium differ from saccharin acid and saccharin sodium dihydrate?

Saccharin acid is the less water-soluble parent sweetener, while saccharin sodium is the soluble salt form. The anhydrous salt is CAS 128-44-9; the dihydrate is CAS 6155-57-3 and contains two water molecules, so buyers should confirm whether a specification is expressed on an anhydrous or dihydrate basis.

Why is Saccharin Sodium used in nickel electroplating?

Electroplating-grade saccharin sodium acts as a Class I brightener, grain refiner, and stress reliever in nickel baths. At low use levels it improves deposit brightness, ductility, and surface smoothness without introducing calories or sweetness-related function.

Why is Saccharin Sodium suitable for sugar-free foods and baked goods?

It is about 300 to 500 times sweeter than sucrose, non-caloric, and more heat-stable than aspartame, so it can be used in sugar-free beverages, confectionery, and baked products. Its high water solubility also makes it easy to dose in liquid and solid formulations.

What roles does Saccharin Sodium play in oral care, pharmaceuticals, and animal feed?

In toothpaste and mouthwash it masks bitter or unpleasant ingredients without promoting tooth decay. Pharmaceutical syrups and chewable tablets use it as a non-caloric taste-masking agent, while feed formulations use it in controlled amounts to improve palatability and intake.

Product Description

Saccharin Sodium CAS 128-44-9 is the water-soluble sodium salt of saccharin, also known as sodium o-benzosulfimide, with molecular formula C7H4NNaO3S, molecular weight about 205.17 and EINECS 204-886-1.

Synonyms: Soluble Saccharin; Sodium o-benzosulfimide; 1,2-Benzisothiazol-3(2H)-one 1,1-dioxide sodium salt; Sodium 1,1-dioxo-1,2-benzothiazol-3-olate; Saccharin soluble.

CAS: 128-44-9.

It has the molecular formula C7H4NNaO3S and a molecular weight of about 205.17 g/mol.

It appears as a white crystalline powder and is freely soluble in water.

It is about 300 to 500 times sweeter than sucrose, non-caloric and more heat-stable than aspartame.

The anhydrous salt is CAS 128-44-9, while the dihydrate is CAS 6155-57-3 and contains two water molecules.

In food and beverage use, it is a high-intensity sweetener for sugar-free drinks, confectionery and baked products.

In oral care, it masks bitter or unpleasant ingredients in toothpaste and mouthwash without promoting tooth decay.

In pharmaceuticals, it is used as a non-caloric taste-masking agent in syrups and chewable tablets.

Electroplating-grade material acts as a Class I brightener, grain refiner and stress reliever in nickel baths.

Feed formulations use controlled amounts to improve palatability and feed intake.

Buyers should confirm whether the specification is expressed on an anhydrous or dihydrate basis.

A typical specification controls assay, water content, melting-related identity, and impurity limits.

Confirm appearance, assay, water content, benzoic and p-sulfamoylbenzoic acid impurities, heavy metals and arsenic limits.

Store in a cool, dry, ventilated area in closed packaging away from direct sunlight and moisture.

Confirm packaging with the requested quantity and destination requirements.
