Description

General description

Methyl linoleate, non-conjugated, is more easily oxidized than conjugated methyl linoleate .

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Application

The oxidation of methyl linoleate in organic solution and phosphatidylcholine (PC) in liposomal membranes induced by an azo initiator has often been used as a model for lipid peroxidation in vivo .

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
