Chemical Structure

1-(Chloromethyl)-3-vinylbenzene CAS 39833-65-3 chemical structure

Description

1-(Chloromethyl)-3-vinylbenzene (CAS 39833-65-3), molecular formula C9H9Cl and molecular weight 152.62 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(Chloromethyl)-3-vinylbenzene (C9H9Cl) is characterized by chlorine substitution, an aromatic ring system. 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 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.
