Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Methyl (E)-2-((2-(3-cyanopyrazolo[1,5-a]pyrido[3,4-e]pyrimidin-6-yl)vinyl)amino)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.36 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.
CATO supplies Methyl (E)-2-((2-(3-cyanopyrazolo[1,5-a]pyrido[3,4-e]pyrimidin-6-yl)vinyl)amino)benzoate (CAS 338411-85-1), a certified reference material (molecular formula C20H14N6O2, MW 370.36 g/mol) for analytical method development and quality control.
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.
