Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 267.29 g/mol gives 11K-030 303145-73-5 7-[(E)-2-(4-methoxyphenyl)ethenyl]-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 11K-030 303145-73-5 7-[(E)-2-(4-methoxyphenyl)ethenyl]-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine (CAS 303145-73-5), a certified reference material (molecular formula C14H13N5O, MW 267.29 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, 11K-030 303145-73-5 7-[(E)-2-(4-methoxyphenyl)ethenyl]-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 267.29 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.
