Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 3121.51 g/mol gives Liraglutide(8-31)TFA Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Liraglutide(8-31)TFA Salt (CAS CATO-C4X-19922), a certified reference material (molecular formula C139H220N34O40C2HF3O2, MW 3121.51 g/mol) for analytical method development and quality control.
The molecular framework of Liraglutide(8-31)TFA Salt (C139H220N34O40C2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
