About Chlorides

Buy ferric chloride, magnesium chloride hexahydrate, and calcium chloride from Alliance Chemical in Reagent, FCC/USP, and Technical grades.

Products In This Collection

This collection includes ferric chloride 40% Reagent Grade (CAS 7705-08-0, specific gravity 1.19), magnesium chloride hexahydrate FCC/USP Grade (CAS 7791-18-6, 99.0–100.5% assay), and calcium chloride Technical Grade (CAS 10043-52-4).

Common Applications

Ferric chloride 40% is the standard coagulant for water treatment, a primary etchant for PCB manufacturing, and a wastewater flocculant. Magnesium chloride hexahydrate serves as a firming agent in food processing, pharmaceutical excipient, de-icing agent, and dust control chemical. Calcium chloride is used for road de-icing, concrete acceleration, industrial desiccation, and dust suppression.

Why Buy From Alliance Chemical

All chloride products ship with Safety Data Sheets (SDS) and lot-specific Certificates of Analysis (COA). Alliance Chemical provides 1-2 business day shipping with no minimum order.

Frequently Asked Questions

What is the difference between ACS and Reagent grade chlorides?
ACS grade chlorides meet standards set by the American Chemical Society, ensuring high purity suitable for laboratory and research use. Reagent grade is slightly lower in purity but still adequate for most industrial applications. Alliance Chemical provides both grades to meet diverse industry needs.
How are chloride salts used in water treatment?
Chloride salts like ferric chloride are used as coagulants in water and wastewater treatment processes. They help to aggregate contaminants, making them easier to remove through filtration. Alliance Chemical offers these in various concentrations suitable for different scales of water treatment.
What are the safety considerations when handling chloride salts?
When handling chloride salts, it is vital to wear appropriate PPE and follow safety data sheet (SDS) guidelines to avoid skin and eye irritation. Store them in a cool, dry place to prevent degradation. Alliance Chemical ensures all products come with comprehensive safety information.
Can calcium chloride be used in food processing?
Yes, calcium chloride is often used in food processing for preservation and as a firming agent. It is crucial to use food-grade quality to ensure safety, which Alliance Chemical readily supplies.
How does magnesium chloride help in road de-icing?
Magnesium chloride lowers the freezing point of water, making it effective in melting ice on roads. It is less corrosive compared to other salts, making it more environmentally friendly. Alliance Chemical provides various grades suitable for different de-icing needs.
Which grade of chloride salts is best for metal surface treatment?
For metal surface treatments, a high-purity grade such as ACS or analytical reagent is recommended for consistent results. Alliance Chemical offers these high-quality grades to ensure optimal surface treatment and finishing.
Are chloride salts safe for use in concrete acceleration?
Chloride salts can be used in concrete acceleration to speed up setting times, particularly in cold conditions. However, it is important to follow usage guidelines to avoid any compromise to structural integrity. Alliance Chemical ensures quality products for safe use in construction applications.
What storage tips are recommended for chloride salts?
Chloride salts should be stored in a dry, cool environment away from incompatible substances to prevent unwanted chemical reactions. Ensure containers are tightly sealed to maintain product integrity. Alliance Chemical provides detailed storage instructions with every purchase.
