Description

Compared with other compounds in its class, the molecular weight of 209.07 g/mol gives (1S,3R)-3-(2,2-Dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1S,3R)-3-(2,2-Dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid (CAS 55701-09-2), molecular formula C8H10Cl2O2 and molecular weight 209.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1S,3R)-3-(2,2-Dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid (C8H10Cl2O2) 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. 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.
