Chemical Structure

Dinophysistoxin 2 CAS 139933-46-3 chemical structure

Description

Dinophysistoxin 2 (CAS 139933-46-3), molecular formula C44H68O13 and molecular weight 805.00 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dinophysistoxin 2 (C44H68O13) 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 805.00 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
