Chemical Structure
Description
Amyloid Bri Protein Precursor277 (89-106) trifluoroacetate salt (CAS 1802078-21-2), molecular formula C87H141N21O30SC2HF3O2 and molecular weight 2107.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Amyloid Bri Protein Precursor277 (89-106) trifluoroacetate salt (C87H141N21O30SC2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
