(E)-N-methoxy-N'-(7-(4-phenoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)formimidamide CAS 303145-99-5 chemical structure

Description

The occurrence of (E)-N-methoxy-N'-(7-(4-phenoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)formimidamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-N-methoxy-N'-(7-(4-phenoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)formimidamide (CAS 303145-99-5), a certified reference material (molecular formula C19H16N6O2, MW 360.37 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (E)-N-methoxy-N'-(7-(4-phenoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)formimidamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
