Description

Zinc Fumarate CAS NO 52723-61-2 is an inorganic salt of fumaric acid, valued for its role as a stable and bioavailable source of zinc. This compound is essential in applications where controlled mineral release and compatibility with organic matrices are required. It serves as a critical functional ingredient for manufacturers in the nutritional supplement, food fortification, and pharmaceutical industries.

Application

• Dietary Supplements & Nutraceuticals: Used as a zinc mineral source in tablet, capsule, and powder formulations for its stability and bioavailability.
• Food & Beverage Fortification: Incorporated into cereals, flour, health drinks, and meal replacements as a nutritional additive to prevent zinc deficiency.
• Pharmaceutical Preparations: Serves as an active pharmaceutical ingredient (API) or excipient in solid dosage forms like tablets and lozenges.
• Animal Feed & Pet Nutrition: Acts as a zinc supplement in premixes and complete feeds to support animal health, growth, and immune function.
• Cosmetics & Personal Care: Utilized in topical creams, ointments, and lotions for its skin-protective and astringent properties.
• Polymer & Material Science: Functions as a catalyst or stabilizer in certain polymerization processes and as a flame retardant synergist.

Quality Control

Our Zinc Fumarate is manufactured under a strict quality management system. Each batch is tested to ensure it meets specifications for identity, purity, and heavy metal content, aligning with standards such as USP-NF, FCC, and relevant pharmacopoeial monographs. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and flow properties.
