Sodium Prop-2-yne-1-sulfonate For Brightener CAS 55947-46-1

Products Description

Sodium prop-2-yne-1-sulfonate (CAS No.: 55947-46-1), also known as 2-Propyne-1-sulfonic acid sodium salt, has a molecular formula of C₃H₃NaO₃S and a molecular weight of 142.11.
The melting point of sodium prop-2-yne-1-sulfonate is approximately 220°C (decomposes), and its density is 1.04 g/mL (25°C, aqueous solution). Its aqueous solution is weakly acidic (pH 2–4), completely miscible with water, and slightly soluble in organic solvents such as methanol. The molecular structure contains alkynyl and sulfonic acid groups, endowing it with the chemical reactivity of both unsaturated hydrocarbons and sulfonates, capable of undergoing addition, esterification, and nucleophilic substitution reactions.

Basic Info

Uses

In industrial applications, sodium prop-2-yne-1-sulfonate serves as a low-area brightener and leveling agent in nickel plating at a typical dosage of 10–200 mg/L. It significantly enhances the brightness and leveling properties of the coating in low-current-density areas while reducing brittleness. As a nucleophilic reagent or intermediate, it participates in olefin addition, esterification, and carbon-carbon bond formation reactions, contributing to the synthesis of sulfur-containing organic compounds.

Safety Information

It is irritating to the skin and eyes (R36/38), and a few studies suggest that it may have a potential carcinogenic risk (R40). Protective equipment should be worn during operation to avoid direct contact.
When storing, it should be protected from light and moisture, away from acids and oxidants, and it is recommended to be protected by inert gas.
