Request SDS →Ammonium chloride (CAS 12125-02-9, NH4Cl), also called sal ammoniac, is a white crystalline salt. It is used as a soldering and galvanizing flux, in dry-cell (Leclanché) batteries, in electroplating and zinc/tin plating, as a mordant in textile dyeing, as a pickling agent, and as a nitrogen fertilizer.
Frequently Asked Questions
What is ammonium chloride technical grade used for?
Technical-grade ammonium chloride (NH4Cl, sal ammoniac) is used as a soldering and galvanizing flux for zinc and tin plating, as the electrolyte in Leclanche zinc-carbon dry-cell batteries, in electroplating and electrolytic-refining baths, as a mordant in textile dyeing and printing, as a pickling agent, and as a nitrogen fertilizer source. Sold as a white crystalline salt in bulk industrial quantities.
What is the difference between treated and untreated ammonium chloride?
Treated ammonium chloride is processed with an anti-caking additive to reduce moisture absorption and clumping during storage and bulk handling, since untreated NH4Cl is hygroscopic and tends to cake. Both share CAS 12125-02-9 and the same NH4Cl chemistry; the treated grade is preferred where free-flowing material is needed for metering or flux application. Request the product CoA and SDS for the specific treated technical-grade specification.
What are the different grades of ammonium chloride?
Ammonium chloride is commonly offered in technical/industrial grade (flux, plating, fertilizer), and higher-purity reagent/ACS and USP grades for analytical and pharmaceutical applications. This product is the technical (treated) grade intended for industrial flux, battery, plating, and textile use. Contact us for the grade and packaging that match your process.
What is the chemical formula and CAS number of ammonium chloride?
Ammonium chloride is NH4Cl (CAS 12125-02-9), a white crystalline inorganic salt with a molar mass of about 53.49 g/mol. It is classified under HS code 2827.10 for international trade. Identity is confirmed on the product Certificate of Analysis.
How is bulk ammonium chloride packaged and what is the cost?
Technical-grade ammonium chloride is supplied in bulk industrial packaging such as bags, drums, supersacks, and bulk loads to manufacturers. Pricing depends on grade, volume, and packaging, so request a bulk quote rather than a list price. We can provide the SDS and CoA with your quote.
