Chemical Structure
Description
The molecular framework of Taurine Ethyl Ester Trifluoroacetate (C4H11NO3SC2HF3O2) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, 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.
CATO supplies Taurine Ethyl Ester Trifluoroacetate (CAS 78723-71-4 (free base)), a certified reference material (molecular formula C4H11NO3SC2HF3O2, MW 267.22 g/mol) for analytical method development and quality control.
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.
