(3-(Di(pyridin-2-yl)methylene)cyclopenta-1,4-dien-1-yl)di(pyridin-2-yl)methanol CAS 1740-22-3

Description

The occurrence of (3-(Di(pyridin-2-yl)methylene)cyclopenta-1,4-dien-1-yl)di(pyridin-2-yl)methanol 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 (3-(Di(pyridin-2-yl)methylene)cyclopenta-1,4-dien-1-yl)di(pyridin-2-yl)methanol (CAS 1740-22-3), a certified reference material (molecular formula C27H20N4O, MW 416.47 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (3-(Di(pyridin-2-yl)methylene)cyclopenta-1,4-dien-1-yl)di(pyridin-2-yl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 416.47 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.
