(1-Methyl-1H-pyrrol-2-yl)(2-(pyrimidin-2-yl)-2,9-diazaspiro[5.5]undecan-9-yl)methanone CAS 959497-76-8

Description

The occurrence of (1-Methyl-1H-pyrrol-2-yl)(2-(pyrimidin-2-yl)-2,9-diazaspiro[5.5]undecan-9-yl)methanone 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 (1-Methyl-1H-pyrrol-2-yl)(2-(pyrimidin-2-yl)-2,9-diazaspiro[5.5]undecan-9-yl)methanone (CAS 959497-76-8), a certified reference material (molecular formula C19H25N5O, MW 339.43 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (1-Methyl-1H-pyrrol-2-yl)(2-(pyrimidin-2-yl)-2,9-diazaspiro[5.5]undecan-9-yl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.43 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.

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.
