Chemical Structure

1,3-Diphenyladamantane CAS 40189-21-7 chemical structure

Description

Owing to a polycyclic aromatic system, 1,3-Diphenyladamantane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.43 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.

1,3-Diphenyladamantane (CAS 40189-21-7) is a high-purity analytical reference standard with the molecular formula C22H24 and a molecular weight of 288.43 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 1,3-Diphenyladamantane 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.
