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.
1,3-Benzenediol-4,4-[6-[1-(phenylmethyl)-1-H-pyrrol-2-yl]-1,3,5-triazine-2,4-diyl]bisor2-(1-Benzyl-1H-pyrrol-2-yl)-4,6-bis(2,4-dihydroxyphenyl)-1,3,5-triazine (CAS 916334-62-8), molecular formula C26H20N4O4 and molecular weight 452.46 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1,3-Benzenediol-4,4-[6-[1-(phenylmethyl)-1-H-pyrrol-2-yl]-1,3,5-triazine-2,4-diyl]bisor2-(1-Benzyl-1H-pyrrol-2-yl)-4,6-bis(2,4-dihydroxyphenyl)-1,3,5-triazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.46 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).
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.
