Chemical Structure
Description
The occurrence of Nonachlor is closely related to chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Nonachlor (CAS 3734-49-4), molecular formula C10H5Cl9 and molecular weight 444.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine substitution, an aromatic ring system, Nonachlor is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.22 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), Nonachlor 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.
