Chemical Structure

n-Tetracosane-d50 CAS 16416-32-3 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.

n-Tetracosane-d50 (CAS 16416-32-3), molecular formula C24D50 and molecular weight 388.96 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, n-Tetracosane-d50 (C24D50) contains deuterium isotope labeling, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 25.0, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 388.96 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), n-Tetracosane-d50 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.
