Chemical Structure

Levothyroxine D3 CAS CATO-C4X-167856 chemical structure

Description

CATO manufactures Levothyroxine D3 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Levothyroxine D3 (CAS CATO-C4X-167856), molecular formula C15H8D3I4NO4 and molecular weight 779.89 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Levothyroxine D3 (C15H8D3I4NO4) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
