Chemical Profile

Product Overview

Sodium Bisulfite 15% Technical Grade is a pre-diluted aqueous solution of sodium bisulfite (NaHSO3) prepared with high-purity deionized water. This 15% concentration provides a convenient, ready-to-use form that eliminates the need for on-site dilution of concentrated stock. Appearance: Clear, colorless to pale yellow liquid with sulfur odor. This Technical Grade product is manufactured for industrial and commercial applications where high purity is required for consistent performance.

Supplied by Alliance Chemical in sizes ranging from 1 quart to 330-gallon IBC totes, this solution is ideal for operations requiring consistent 15% strength with minimal handling risk compared to higher concentrations.

Pulp & Paper Processing: Bleaching agent and lignin solubilizer in pulp production and paper manufacturing.
Photography & Developing: Fixing agent and preservative in photographic processing solutions.

Safety Precautions

Sodium Bisulfite solutions release sulfur dioxide gas, which is irritating to the respiratory tract. Handle in well-ventilated areas. Do not mix with acids — this accelerates SO2 release. Store in tightly sealed HDPE containers in a cool, dry location.

PPE Requirements: Wear chemical-resistant gloves, safety goggles, and respiratory protection if ventilation is inadequate. In case of inhalation, move to fresh air immediately. In case of skin or eye contact, rinse with water for at least 15 minutes. Refer to the Safety Data Sheet (SDS) for full handling and emergency procedures.

Shipping: UN 2693, Bisulfites, aqueous solutions, Class 8, PG III.
