Chemical Structure

1,1,1,2-Tetrachloroethane CAS 630-20-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,1,2-Tetrachloroethane.

1,1,1,2-Tetrachloroethane (CAS 630-20-6), molecular formula C2H2Cl4 and molecular weight 167.85 g/mol, is a CATO reference standard with documented purity and traceability.

1,1,1,2-Tetrachloroethane (C2H2Cl4) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1,1,1,2-Tetrachloroethane 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.
