Chemical Structure
Description
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.
Tulathromycin A-d7 (CAS 2734920-62-6), molecular formula C41H72D7N3O12 and molecular weight 813.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Tulathromycin A-d7 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 813.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
