Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(((1H-Pyrrol-2-yl)methylene)hydrazono)-1,2-diphenylethanone (CAS 201161-08-2), molecular formula C19H15N3O and molecular weight 301.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(((1H-Pyrrol-2-yl)methylene)hydrazono)-1,2-diphenylethanone (C19H15N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 301.34 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
