Chemical Structure

Pcb No. 122 CAS 76842-07-4 chemical structure

Description

Based on its molecular formula C12H5Cl5, Pcb No. 122 contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 326.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Pcb No. 122 (CAS 76842-07-4) is a high-purity analytical reference standard with the molecular formula C12H5Cl5 and a molecular weight of 326.43 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Pcb No. 122 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.
