Description

thoughtful mini-steps:

Manganese chloride tetrahydrate (CAS 13446-34-9), also sold as manganous chloride tetrahydrate, is an inorganic manganese salt used across industrial, agricultural, and life science sectors. It functions primarily as a micronutrient supplement and process reagent.

In animal feed and agriculture, it supplies manganese as a trace mineral additive to support livestock nutrition. It is incorporated into premixes and compound feed at defined inclusion rates to ensure optimal animal health and growth.

Water treatment operations use it as a reagent in manganese greensand filtration systems. Here, it supports the oxidation and removal of dissolved iron and manganese from potable water supplies to meet safety standards.

Pharmaceutical and nutraceutical manufacturers use it as a manganese source in mineral supplement formulations. It also serves as a critical reagent in cell culture media and various biological research applications.

Personal care formulators incorporate it into select cosmetic preparations where controlled manganese ion delivery is required. This versatile chemical is essential for maintaining specific chemical balances in high-end formulations.

Manganese chloride tetrahydrate is supplied as a pink crystalline solid or granular powder. Standard commercial grades include technical, feed-grade, and reagent/ACS grades for laboratory and industrial use.

Pharmaceutical-grade material is available to USP and BP specifications to ensure the highest purity. Packaging typically ranges from laboratory quantities up to bulk bags for large-scale industrial supply.
