Propargyl Alcohol Propoxylate (PAP), a chemical compound with the CAS number 3973-17-9, is a vital ingredient in numerous industrial applications, most notably within the electroplating sector. Its unique chemical structure and properties make it an effective brightener and leveling agent for nickel plating baths, contributing significantly to the aesthetic and functional qualities of plated components. As a dedicated B2B chemical supplier, we aim to provide comprehensive information about such crucial intermediates to our clients.

The chemical name Propargyl alcohol propoxylate precisely describes its synthesis, being a condensation product of propargyl alcohol and propylene oxide. It is typically a colorless to yellowish liquid with a molecular formula of C6H10O2 and a molecular weight of approximately 114.14 g/mol. Key physical properties include a density around 0.98-1.01 g/cm³ at 20°C and a refractive index of approximately 1.4430-1.4455 at 20°C. Its solubility is generally good in water and common polar organic solvents, which is advantageous for incorporation into aqueous electroplating bath formulations. The CAS number 3973-17-9 is the standard identifier for this compound, essential for accurate sourcing and regulatory compliance when you buy PAP.

The primary and most well-known application of PAP is as a component in nickel electroplating baths. Here, it functions as a secondary brightener and a leveling agent. As a brightener, it refines the grain structure of the electrodeposited nickel, leading to a highly lustrous, mirror-like finish. Its leveling capabilities help to smooth out surface imperfections on the substrate, ensuring a uniform and defect-free deposit, even on complex geometries. This dual action is critical for achieving the premium finishes required in automotive applications, consumer electronics, and decorative hardware. Manufacturers seeking to purchase high-quality plating chemicals will find PAP indispensable for meeting these demands. We are a trusted manufacturer and supplier in China, ensuring the purity and efficacy of the PAP we provide.

Beyond its prominent role in nickel plating, PAP and its derivatives can find applications in other areas such as organic synthesis, where it can serve as a reactive intermediate or building block. Its unsaturated functional group and hydroxyl moiety offer versatile reaction pathways. However, its primary industrial utility remains in electroplating. For any business aiming to enhance their plating processes, securing a reliable supply of PAP from a reputable Propargyl Alcohol Propoxylate supplier is crucial. We offer competitive pricing and consistent availability to support your manufacturing operations, ensuring you can easily purchase the quantities you need.

In conclusion, Propargyl Alcohol Propoxylate (CAS 3973-17-9) is a highly valuable chemical intermediate with significant applications in nickel electroplating as both a brightener and a leveling agent. Its properties contribute to superior surface finish, corrosion resistance, and overall product quality. As a leading Chinese manufacturer and supplier, we are committed to providing high-purity PAP to meet the stringent requirements of the global electroplating industry.
