Chemical Structure
Description
1,3,5-Trichloro-2-vinylbenzene (CAS 15270-64-1) is a high-purity analytical reference standard with the molecular formula C8H5Cl3 and a molecular weight of 207.48 g/mol.
Owing to chlorine substitution, an aromatic ring system, 1,3,5-Trichloro-2-vinylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 1,3,5-Trichloro-2-vinylbenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
