Chemical Profile

Product Overview

Ammonium Hydroxide 5% ACS Grade is a pre-diluted aqueous solution of ammonium hydroxide (NH4OH) prepared with high-purity deionized water. This 5% concentration provides a convenient, ready-to-use form that eliminates the need for on-site dilution of concentrated stock. Appearance: Clear, colorless liquid with mild ammonia odor. Meeting ACS Reagent Grade specifications, this product is suitable for analytical and laboratory applications requiring controlled purity and documented impurity limits.

Supplied by Alliance Chemical in sizes ranging from 1 quart to 330-gallon IBC totes, this solution is ideal for operations requiring consistent 5% strength with minimal handling risk compared to higher concentrations.

Safety Precautions

Ammonium Hydroxide releases ammonia vapor which is irritating to eyes, skin, and respiratory tract. Handle in well-ventilated areas or under a fume hood. Store in tightly sealed HDPE containers in a cool, dry location away from acids.

PPE Requirements: Wear chemical-resistant gloves, splash goggles, and a face shield. Use respiratory protection if ventilation is inadequate. In case of inhalation, move to fresh air immediately. In case of eye or skin contact, rinse with water for at least 15 minutes. Refer to the SDS for detailed handling and emergency procedures.

Shipping: Not regulated as a hazardous material for transport (UN 2672 covers ammonia solutions above 10%).

Benefits

Ready-to-Use Solution: Pre-diluted concentration reduces vapor exposure and simplifies safe handling.
Consistent Ammonia Content: Manufactured with high-purity materials for reliable concentration control.
Flexible Packaging: Available from quart bottles to bulk totes for any application scale.
