Chemical Structure

Dinophysistoxin 1 CAS 81720-10-7 chemical structure

Description

Dinophysistoxin 1 (CAS 81720-10-7), molecular formula C45H70O13 and molecular weight 819.03 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dinophysistoxin 1 (C45H70O13) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 819.03 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Dinophysistoxin 1 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.
