Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,4'-(Naphthalene-1,4-diyl)dianiline (CAS 956980-39-5), molecular formula C22H18N2 and molecular weight 310.39 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,4'-(Naphthalene-1,4-diyl)dianiline (C22H18N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 310.39 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 4,4'-(Naphthalene-1,4-diyl)dianiline 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.
