Chemical Structure
Description
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.
(T-4)-[N-[(Carboxy-κO)methyl]-N-methylglycinato(2-)-κN,κO]-4-pyridinylboron (CAS 1104636-72-7), molecular formula C10H11BN2O4 and molecular weight 234.02 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H11BN2O4, (T-4)-[N-[(Carboxy-κO)methyl]-N-methylglycinato(2-)-κN,κO]-4-pyridinylboron contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.02 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.
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.
