Compared with other compounds in its class, the molecular weight of 554.68 g/mol gives CTA 056 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CTA 056 (CAS 1265822-30-7), molecular formula C35H34N6O and molecular weight 554.68 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, CTA 056 (C35H34N6O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 554.68 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).
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.
