DETAILS
Product Description
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.

Frequently Asked Questions (FAQ)
Why should I use a certified Lactose Standard instead of regular lactose powder?
Certified reference standards ensure traceability, reproducibility, and compliance, while regular lactose may contain impurities or moisture that lead to:
Inaccurate calibration during HPLC, LC-MS, or GC analysis.
Failed method validation during audits or regulatory reviews.
Inconsistent results in pharmaceutical quality control.
Our Lactose Standard (≥95%) comes with COA and SDS, ready for compliance with global regulatory requirements.
Which industries commonly use Lactose Standard?
Pharmaceutical Industry: Tablet excipient QC, drug stability studies, inhalation product testing.
Food Industry: Dairy product testing, nutritional labeling, lactose-free formulation validation.
Clinical Research: Enzyme activity studies, lactose metabolism research.
