Chemical Structure
Description
Des-Tyr10-Tirzepatide (CAS CATO-CPTD788680), molecular formula C216H339N47O66 and molecular weight 4650.28 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Des-Tyr10-Tirzepatide (C216H339N47O66) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 71.0, corresponding to approximately 71 ring(s) or double-bond equivalent(s). With a molecular weight of 4650.28 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
