Chemical Structure

H-Trp-Phe-Tyr-Ser(PO3H2)-Pro-Arg-AMC trifluoroacetate salt CAS 1926163-51-0 chemical structure

Description

The occurrence of H-Trp-Phe-Tyr-Ser(PO3H2)-Pro-Arg-AMC trifluoroacetate salt is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

H-Trp-Phe-Tyr-Ser(PO3H2)-Pro-Arg-AMC trifluoroacetate salt (CAS 1926163-51-0) is a high-purity analytical reference standard with the molecular formula C53H62N11O13PC2HF3O2 and a molecular weight of 1206.14 g/mol.

Based on its molecular formula C53H62N11O13PC2HF3O2, H-Trp-Phe-Tyr-Ser(PO3H2)-Pro-Arg-AMC trifluoroacetate salt contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1206.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
