Home » Portfolio Items » Lactose Standard | CAS 63-42-3
Lactose (CAS 63-42-3) is a naturally occurring disaccharide sugar composed of glucose and galactose, commonly found in milk and dairy products. It plays a crucial role in the food, pharmaceutical, and biotechnology industries. In pharmaceuticals, lactose is one of the most widely used excipients in tablets, capsules, and inhalation powders due to its stability, solubility, and compatibility with active ingredients.
As an analytical reference material, Lactose Standard is essential for method validation, instrument calibration, and routine quality control (QC) across diverse laboratory workflows.
This high-purity Lactose Standard (≥95%) is produced under ISO/IEC 17025 and GMP-compliant processes to ensure consistent, traceable, and reliable analytical performance.
