Chemical Structure

(2,5-Dimethylphenyl)(isoquinolin-4-yl)methanone CAS 1187171-85-2 chemical structure

Description

Structurally, (2,5-Dimethylphenyl)(isoquinolin-4-yl)methanone (C18H15NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 261.32 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies (2,5-Dimethylphenyl)(isoquinolin-4-yl)methanone (CAS 1187171-85-2), a certified reference material (molecular formula C18H15NO, MW 261.32 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.
