Chemical Structure
Description
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.
CATO supplies ([ring-D5]Phe3)-Octreotide acetate salt (CAS 1134880-79-7), a certified reference material (molecular formula C49H61D5N10O10S2C2H4O2, MW 1084.33 g/mol) for analytical method development and quality control.
Structurally, ([ring-D5]Phe3)-Octreotide acetate salt (C49H61D5N10O10S2C2H4O2) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 24.5, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 1084.33 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.
