Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((4-(1H-1,2,4-triazol-1-yl)phenyl)amino)-1-(4-methoxyphenyl)propan-1-one.
3-((4-(1H-1,2,4-triazol-1-yl)phenyl)amino)-1-(4-methoxyphenyl)propan-1-one (CAS 763126-06-3), molecular formula C18H18N4O2 and molecular weight 322.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-((4-(1H-1,2,4-triazol-1-yl)phenyl)amino)-1-(4-methoxyphenyl)propan-1-one (C18H18N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 322.36 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
