Chemical Structure
Description
The occurrence of Thymidine3-monophosphateammoniumsalt is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Thymidine3-monophosphateammoniumsalt (CAS 40705-89-3), a certified reference material (molecular formula C10H15N2O8PH3N, MW 339.24 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H15N2O8PH3N, Thymidine3-monophosphateammoniumsalt contains a carbohydrate-derived structure, an amide group, a phosphate ester group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 339.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
