Vitamin D, 25-Hydroxy

Vitamin D, 25-Hydroxy

Vitamin D, 25-Hydroxy is a high-purity reference standard used for pharmaceutical, clinical, and laboratory testing. It represents the main circulating form of vitamin D in the blood and is essential for calibrating assays that measure vitamin D status in patients.

Typical uses include method development, quality control, and assay validation in laboratories performing vitamin D testing. The material is supplied in a stabilized, accurately weighed form to ensure reliable results across multiple analytical runs.

Key features:

• High purity and certified accuracy
• Stabilized for long-term storage
• Suitable for LC-MS, immunoassay, and GC techniques
• Traceability to recognized reference standards

Recommended applications include:

• Calibration of vitamin D, 25-hydroxy assays
• Quality control materials for clinical laboratories
• Method comparison and validation studies

Storage and handling guidance:

• Store in a cool, dry place away from direct light
• Keep container tightly closed when not in use
• Avoid exposure to moisture and high temperatures

Safety and handling: Handle according to standard laboratory safety practices. Avoid inhalation, ingestion, and contact with skin and eyes. Refer to the material safety data sheet for detailed information.

Each lot is accompanied by a certificate of analysis specifying purity, assay value, and storage conditions to meet quality control requirements.
