Chemical Structure

n-Pentacosane-d52 CAS 121578-13-0 chemical structure

Description

n-Pentacosane-d52 (CAS 121578-13-0), molecular formula C25D52 and molecular weight 405.00 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C25D52, n-Pentacosane-d52 contains deuterium isotope labeling, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 405.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), n-Pentacosane-d52 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
