4-(3-Aminopropyl)-5-(3-methoxynaphthalen-2-yl)-1H-pyrazol-3(2H)-one CAS 881040-86-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(3-Aminopropyl)-5-(3-methoxynaphthalen-2-yl)-1H-pyrazol-3(2H)-one.

CATO supplies 4-(3-Aminopropyl)-5-(3-methoxynaphthalen-2-yl)-1H-pyrazol-3(2H)-one (CAS 881040-86-4), a certified reference material (molecular formula C17H19N3O2, MW 297.35 g/mol) for analytical method development and quality control.

4-(3-Aminopropyl)-5-(3-methoxynaphthalen-2-yl)-1H-pyrazol-3(2H)-one (C17H19N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
