Chemical Structure
Description
rac-Liothyronine-15N-13C9 (CAS CATO-C4X-21313), molecular formula N/A and molecular weight 660.90 g/mol, is a CATO reference standard with documented purity and traceability.
rac-Liothyronine-15N-13C9 is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
