Chemical Structure

Tetrachloroethene CAS 127-18-4 chemical structure

Description

The occurrence of Tetrachloroethene is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tetrachloroethene (CAS 127-18-4), a certified reference material (molecular formula C2Cl4, MW 165.83 g/mol) for analytical method development and quality control.

Based on its molecular formula C2Cl4, Tetrachloroethene contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 165.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Tetrachloroethene 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.
