Chemical Structure

54505-72-5 Diethylmalonic acid dichloride Diethylmalonyl dichloride CAS 54505-72-5 chemical structure

Description

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.

CATO supplies 54505-72-5 Diethylmalonic acid dichloride Diethylmalonyl dichloride (CAS 54505-72-5), a certified reference material (molecular formula C7H10Cl2O2, MW 197.06 g/mol) for analytical method development and quality control.

The molecular framework of 54505-72-5 Diethylmalonic acid dichloride Diethylmalonyl dichloride (C7H10Cl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
