Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Dichloro-3-(2-chloroallyl)benzene.
1,2-Dichloro-3-(2-chloroallyl)benzene (CAS 951892-41-4), molecular formula C9H7Cl3 and molecular weight 221.51 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine substitution, an aromatic ring system, 1,2-Dichloro-3-(2-chloroallyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 221.51 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), 1,2-Dichloro-3-(2-chloroallyl)benzene 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.
