Ergocalciferol USP

Ergocalciferol USP is a high-purity form of Vitamin D2 used in pharmaceutical, nutraceutical, and clinical nutrition formulations to support calcium and phosphorus metabolism, bone health, and treatment of Vitamin D deficiency. Compliant with United States Pharmacopeia (USP) standards, it is commonly formulated in oral solid and liquid dosage forms requiring precise potency control.
Ergocalciferol is chemically designated as (3β,5Z,7E,22E)-9,10-Secoestra-5,7,10(19),22-tetraen-3-ol. It appears as a white to pale yellow crystalline powder or oily solid, depending on concentration, and is practically insoluble in water but soluble in fats and organic solvents. Due to its photosensitivity and susceptibility to oxidation, it is handled under controlled conditions.
In pharmaceutical, nutritional, and clinical applications, Ergocalciferol USP is used in:
• Oral capsules, tablets, and liquid drops for Vitamin D supplementation
• Treatment and prevention of Vitamin D deficiency and related disorders
• Fortified foods and medical nutrition products
• Combination formulations with calcium and other minerals
• Pediatric, geriatric, and clinical nutrition applications
• Research involving Vitamin D metabolism and endocrine regulation
Ergocalciferol USP is metabolized in the body to Calcidiol and subsequently to calcitriol, the biologically active form of Vitamin D. It plays an essential role in maintaining normal calcium absorption, bone mineralization, and overall skeletal health.
CarboMer supplies Ergocalciferol USP with control over potency, purity, oxidation markers, residual solvents, and microbial quality. The material meets USP monograph specifications and is suitable for regulated pharmaceutical and nutritional manufacturing.
The material is packaged in sealed, light-resistant, oxygen-protective, tamper-evident containers to preserve stability. Available in laboratory, pilot, and commercial-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and complete traceability.
Each batch is tested for identity (UV, IR), assay (potency), specific rotation, peroxide value, and microbial limits. Technical support is available to assist with formulation strategies, stabilization, and regulatory compliance.
As with all CarboMer supplied fat-soluble vitamins, Ergocalciferol USP is supported by dependable global supply, rigorous quality control, and expert technical guidance to ensure safe, effective, and consistent product development.
