Nitrosylsulfuric Acid Market Reflects Remarkable Growth at 4.2%

Overview

New York, NY – Dec 31, 2025 – The global Nitrosylsulfuric Acid market is projected to grow from approximately USD 88.0 million in 2024 to around USD 132.8 million by 2034, registering a CAGR of 4.2% during the forecast period from 2025 to 2034. Nitrosylsulfuric Acid (CAS 7782-78-7) is a crucial chemical in industrial processes, particularly in chemical synthesis and dye production, where it acts as a key diazotizing agent. This property enables the diazo reaction, which is essential for producing vibrant and durable colors in disperse dyes for the textile industry. Additionally, it serves as a versatile intermediate in nitrosation, oxidation, and oximation reactions, supporting the manufacture of pharmaceuticals, agrochemicals, and other fine chemicals.

Typically, Nitrosylsulfuric Acid is supplied as a 40% solution in 54% sulfuric acid to ensure stability at room temperature, although long-term storage is recommended at +4°C. It has a melting point of -10°C, a boiling point of 333°C, and a density of 1.612 g/mL at 25°C. The compound is strongly acidic (pKa -7.51), exhibits low vapor pressure, and in its pure crystalline form decomposes at 73°C.

Highly reactive and hazardous, Nitrosylsulfuric Acid acts as a strong irritant and is toxic if inhaled, ingested, or in contact with skin and eyes. Its reaction with water is vigorous, releasing toxic nitrogen dioxide (NO₂) gas, with half the theoretical maximum yield produced within 0.14 minutes in the presence of a five-fold water excess. While soluble in concentrated sulfuric acid, it decomposes in water, highlighting the need for careful handling.
