Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 253.68 g/mol gives ethyl 4-chloro-5-ethylpyrrolo[2,1-f][1,2,4]triazine-6-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies ethyl 4-chloro-5-ethylpyrrolo[2,1-f][1,2,4]triazine-6-carboxylate (CAS 310442-94-5), a certified reference material (molecular formula C11H12ClN3O2, MW 253.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, ethyl 4-chloro-5-ethylpyrrolo[2,1-f][1,2,4]triazine-6-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
