Chemical Structure

Pcb No. 138 CAS 35065-28-2 chemical structure

Description

As a certified reference material (CRM), Pcb No. 138 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.

CATO supplies Pcb No. 138 (CAS 35065-28-2), a certified reference material (molecular formula C12H4Cl6, MW 360.88 g/mol) for analytical method development and quality control.

Structurally, Pcb No. 138 (C12H4Cl6) contains chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 360.88 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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