Chemical Structure

Eprinomectin-13CD3 CAS CATO-C4X-21294 chemical structure

Description

Eprinomectin-13CD3 (CAS CATO-C4X-21294), molecular formula C49[13C]H72D3NO14 and molecular weight 918.14 g/mol, is a CATO reference standard with documented purity and traceability.

Eprinomectin-13CD3 (C49[13C]H72D3NO14) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; 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).

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.
