Chemical Structure
Description
Triethyl (2E)-3-Methyl-4-phosphonocrotonate (CAS 39760-56-0), molecular formula C11H21O5P and molecular weight 264.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Triethyl (2E)-3-Methyl-4-phosphonocrotonate (C11H21O5P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
