ATBS or AMPS is an abbreviation for 2-Acrylamido-2-methylpropane sulfonic acid. NAAMPS or NA ATBS is an abbreviation for Sodium Salt 2-Acrylamido-2-methylpropane sulphonic acid. NA ATBS’s unique numerical identifier assigned by the chemical abstracts service CAS is 5165-97-9.

Some of its synonymous are Sodium 2-acrylamido-2-methyl-1-propanesulfonate, 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid sodium, and Sodium acryloyldimethyltaurate.

NAAMPS acts as a commoner when combined with other acrylic monomers like acrylic acid to manufacture polymers. Sodium AMPS improves scrub resistance and dispersant performance of paper coatings and paint emulsions.

The molecular weight of NaATBS is 229.23. The density of NaATBS is 1.2055 g/ ml at 25 degree celsius . NAAMPS is a 50 wt. % solution in water that enables easy handling of the product.
The product is prepared by reacting 2-acrylamido-2-methylpropanesulphonic acid or ATBS with caustic soda solution.

Sodium Salt 2-Acrylamido-2-Methylpropane Sulfonic Acid CAS 5165-97-9 or NA ATBS don’t easily get vaporized at its low temperature point to form an ignitable mixture in air, so the flash point property is not applicable to it.
NAATBS’s convenient storage, packaging, and logistics provide the necessary ease and flexibility in formulations to produce high-performance polymers. NAAMPS are delivered in three different grades which include 2403, 2405, and 2407 which are derived from their expected performance characteristics and the polymerization molecular weight.

The most common industrial applications of Sodium Salt 2-Acrylamido-2-Methylpropanesulfonic Acid CAS 5165-97-9 are in adhesives to improve pressure-sensitive formulation strength, in water treatment to inhibit calcium, magnesium, and silica scale formation, in personal care products for making diapers, in the textile industry as textile sizing agent and a non-woven emulsion binder, in oil fields as a friction reducer, in acrylic fiber to provide dye receptivity and in the construction site to inhibit fluid loss.

A hydrophilic compound such as NAAMPS or NAATBS can also be used as a dopant. For conducting polymers, Sodium Salt 2-Acrylamido-2-Methylpropane Sulfonic Acid CAS 5165-97-9 acts as a protonating agent.

In order to conduct the water purification process, polyelectrolyte copolymer gels are utilized; for the formation of polyelectrolyte copolymer gels, Sodium Salt 2-Acrylamido-2-Methylpropane Sulfonic Acid is used; NAATBS can also have potential application in the field of bioengineering and biomedical products.

Sodium salt 2-acrylamido-2-methylpropane sulfonic acid is one of the sulfonic acid monomers. It produces monomers, such as polyacrylamide co-polymers, poly(AMPS), AMPS-functionalized polymers, and hydrogels.
Na amps are added to adhesives to boost strength, especially in pressure-sensitive formulations. For water treatment, they prevent scale formation from calcium, magnesium, and silica. They are used in making diapers for personal care products, as a textile sizing agent, and as a non-woven emulsion binder in the textile industry. They are also friction reducers in oil fields, aid dye receptivity in acrylic fiber production, and inhibit fluid loss at construction sites.
C7H13NO4S is the chemical formula for NAAMPS.
NaAMPS is flexible enough to produce high-performance polymers due to its convenient storage, logistics, and packaging properties. Besides, it enhances scrub resistance and dispersant performance of paint emulsions and paper coatings.
Na amps use cooling towers, boilers, and precipitating solids in industrial and mining effluents to inhibit calcium, magnesium, and silica scale formation.
NAAMPS is used in hydrogels for tissue engineering and drug delivery systems. These hydrogels mimic the extracellular matrix, fostering cell growth and proliferation. They are also used in wound dressings and studying controlled drug release, acting as carriers for therapeutic agents.
Sodium Salt 2-Acrylamido-2-Methylpropanesulfonic Acid is typically supplied as a dry powder or in solution form. The powder form must be stored in a cool, dry place away from direct sunlight and moisture to prevent degradation and maintain its purity and stability.
