Chemical Structure

FK-506-13C,D4 (Major) (Tacrolimus) CAS CATO-C4X-130060 chemical structure

Description

FK-506-13C,D4 (Major) (Tacrolimus) (CAS CATO-C4X-130060) is a high-purity analytical reference standard with the molecular formula C43[13C]H65D4NO12 and a molecular weight of 809.04 g/mol.

Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, FK-506-13C,D4 (Major) (Tacrolimus) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 809.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), FK-506-13C,D4 (Major) (Tacrolimus) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
