Chemical Structure
Description
o-Terphenyl-d14 (CAS 5142-67-6), molecular formula C18D14 and molecular weight 244.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a polycyclic aromatic system, o-Terphenyl-d14 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures o-Terphenyl-d14 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
