2-(Chloromethyl)-1,4-naphthalenedione CAS 43027-41-4

Description

Compared with other compounds in its class, the molecular weight of 206.63 g/mol gives 2-(Chloromethyl)-1,4-naphthalenedione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(Chloromethyl)-1,4-naphthalenedione (CAS 43027-41-4), a certified reference material (molecular formula C11H7ClO2, MW 206.63 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-(Chloromethyl)-1,4-naphthalenedione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.63 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.
