2,5-Dimethyl-1-(naphthalen-1-yl)-1h-pyrrole-3-carbaldehyde CAS 347332-11-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Dimethyl-1-(naphthalen-1-yl)-1h-pyrrole-3-carbaldehyde.

CATO supplies 2,5-Dimethyl-1-(naphthalen-1-yl)-1h-pyrrole-3-carbaldehyde (CAS 347332-11-0), a certified reference material (molecular formula C17H15NO, MW 249.31 g/mol) for analytical method development and quality control.

Structurally, 2,5-Dimethyl-1-(naphthalen-1-yl)-1h-pyrrole-3-carbaldehyde (C17H15NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 249.31 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
