Description
Compared with other compounds in its class, the molecular weight of 636.78 g/mol gives Ethyl 2-(1,3-dimethyl-2,4-dioxo-6-(2-(tritylthio)ethyl)-2,3,4,6-tetrahydro-1H-pyrrolo[3,4-d]pyrimidin-5-yl)thiazole-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-(1,3-dimethyl-2,4-dioxo-6-(2-(tritylthio)ethyl)-2,3,4,6-tetrahydro-1H-pyrrolo[3,4-d]pyrimidin-5-yl)thiazole-4-carboxylate (CAS 1614252-42-4) is a high-purity analytical reference standard with the molecular formula C35H32N4O4S2 and a molecular weight of 636.78 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-(1,3-dimethyl-2,4-dioxo-6-(2-(tritylthio)ethyl)-2,3,4,6-tetrahydro-1H-pyrrolo[3,4-d]pyrimidin-5-yl)thiazole-4-carboxylate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 636.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
