Chemical Structure

Dibutyl [2,2'-biquinoline]-4,4'-dicarboxylate CAS 1181-24-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 456.53 g/mol gives Dibutyl [2,2'-biquinoline]-4,4'-dicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dibutyl [2,2'-biquinoline]-4,4'-dicarboxylate (CAS 1181-24-4), molecular formula C28H28N2O4 and molecular weight 456.53 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Dibutyl [2,2'-biquinoline]-4,4'-dicarboxylate (C28H28N2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Dibutyl [2,2'-biquinoline]-4,4'-dicarboxylate 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.
