Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(3-methyl-1,2,4-oxadiazol-5-yl)cyclohexan-1-one.
4-(3-methyl-1,2,4-oxadiazol-5-yl)cyclohexan-1-one (CAS 1339256-33-5) is a high-purity analytical reference standard with the molecular formula C9H12N2O2 and a molecular weight of 180.20 g/mol.
Structurally, 4-(3-methyl-1,2,4-oxadiazol-5-yl)cyclohexan-1-one (C9H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 180.20 g/mol, it falls into the medium-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.
