Phosphatidylcholine (Soy) Certified Reference Material (CRM) is supplied as a pharmaceutical secondary standard for analytical quality control, calibration, and method validation. Derived from soy lecithin sources, phosphatidylcholine is a major phospholipid component of biological membranes and is commonly used as a marker compound in pharmaceutical, nutraceutical, and lipid analysis.

This reference material is traceable to both European Pharmacopoeia (Ph. Eur. Y0001950) and United States Pharmacopeia (USP 1535755) standards, supporting use in regulated laboratory environments. It is suitable for pharmaceutical testing, lipid profiling, formulation development, and quality control of products containing phospholipids or lecithin-derived ingredients.

Secondary standards provide a convenient and cost-effective alternative to primary standards while maintaining traceability to authoritative references. Production and certification are performed in accordance with ISO 17034 and ISO/IEC 17025, and a certificate of analysis is available to support regulatory compliance and analytical documentation.

Shipping and Storage Notice
Please note that shipping and long-term storage conditions for certified reference materials may differ. Manufacturers determine the most appropriate shipping method based on product stability and shipping data. Some CRM standards may ship at ambient temperature even though recommended long-term storage conditions are refrigerated or frozen. This does not affect product integrity when handled according to manufacturer documentation.
