Chemical Structure

Cyclopropanecarboxylic acid, 1-[(4-chlorophenoxy)methyl] CAS 1780867-35-7 chemical structure

Description

CATO supplies Cyclopropanecarboxylic acid, 1-[(4-chlorophenoxy)methyl] (CAS 1780867-35-7), a certified reference material (molecular formula C11H11ClO3, MW 226.66 g/mol) for analytical method development and quality control.

Structurally, Cyclopropanecarboxylic acid, 1-[(4-chlorophenoxy)methyl] (C11H11ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 226.66 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
