Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Hepta-1,6-diene-2,6-diyldibenzene.
Hepta-1,6-diene-2,6-diyldibenzene (CAS 27905-65-3) is a high-purity analytical reference standard with the molecular formula C19H20 and a molecular weight of 248.36 g/mol.
Owing to a polycyclic aromatic system, Hepta-1,6-diene-2,6-diyldibenzene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 248.36 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 Hepta-1,6-diene-2,6-diyldibenzene 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.
