Chemical Structure

Methyl 3,5-dichloro-4-isopropoxybenzoate CAS 856165-88-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 263.12 g/mol gives Methyl 3,5-dichloro-4-isopropoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 3,5-dichloro-4-isopropoxybenzoate (CAS 856165-88-3), a certified reference material (molecular formula C11H12Cl2O3, MW 263.12 g/mol) for analytical method development and quality control.

Structurally, Methyl 3,5-dichloro-4-isopropoxybenzoate (C11H12Cl2O3) 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 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 263.12 g/mol, it falls into the medium-molecular-weight range. 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.
