Overview
Lithium nitrate (CAS 7790-69-4 ) is an inorganic lithium salt used across agricultural, food, and pharmaceutical supply chains as a stabilizing and preservative agent. Its oxidizing character makes it relevant in formulations where controlled reactivity and ionic balance are required.
In agriculture, lithium nitrate functions as a micronutrient source and soil amendment component, supporting lithium delivery in specialty fertilizer blends where trace mineral correction is required.
Food-grade applications include use as a stabilizer and preservation aid in processed formulations, where it contributes to shelf-life extension and product integrity for various industrial food processes.
Pharmaceutical manufacturers incorporate it into preparations where lithium salt delivery is specified, particularly in formulations requiring precise ionic dosing for specialized medicinal applications.
It also appears in analytical and quality control reagents used by QA laboratories in food and pharma environments, often meeting ACS standards for laboratory use and chemical analysis.
Lithium nitrate is supplied as a white crystalline powder or granular solid. Standard commercial grades include technical, food-grade, and pharmaceutical-grade material, with the latter conforming to USP or Ph.Eur. specifications.
Packaging is typically available in small drums or bulk quantities to suit both formulation-scale and industrial procurement requirements, ensuring safe handling and storage of the oxidizing material.
