Chemical Structure

n-Heneicosane-d44 CAS 39756-37-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies n-Heneicosane-d44 (CAS 39756-37-1), a certified reference material (molecular formula C21D44, MW 340.85 g/mol) for analytical method development and quality control.

n-Heneicosane-d44 (C21D44) contains deuterium isotope labeling, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures n-Heneicosane-d44 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.
