Chemical Structure
Description
L-Thyroxine sodium salt pentahydrate, 98% (CAS 6106-07-6) is a high-purity analytical reference standard with the molecular formula C15H10I4NO4NaH2O and a molecular weight of 816.85 g/mol.
Owing to a salt form, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, L-Thyroxine sodium salt pentahydrate, 98% is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 816.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures L-Thyroxine sodium salt pentahydrate, 98% 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.
