Chemical Structure

1,2-Bis(4-(trifluoromethyl)phenyl)ethyne CAS 119757-51-6 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 1,2-Bis(4-(trifluoromethyl)phenyl)ethyne.

1,2-Bis(4-(trifluoromethyl)phenyl)ethyne (CAS 119757-51-6), molecular formula C16H8F6 and molecular weight 314.23 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H8F6, 1,2-Bis(4-(trifluoromethyl)phenyl)ethyne contains fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 314.23 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.

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), 1,2-Bis(4-(trifluoromethyl)phenyl)ethyne 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.
