About Ochratoxin A-D5

Listed under CAS 666236-28-8, Ochratoxin A-D5 is a stable isotope labelled analogue related to Ochratoxin a available from Vaqora Chemicals. Its molecular formula is C20H18ClNO6 and its molecular weight is 408.8 g/mol.

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

We offer Ochratoxin A-D5 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
