Description
CATO supplies 254737-87-6 EEP77N970Y BMS-248360 UNII-EEP77N970Y (1,1'-Biphenyl)-2-sulfonamide, 4'-((2-butyl-4-oxo-1,3-diazaspiro(4.4)non-1-en-3-yl)methyl)-N-(3,4-dimethyl-5-isoxazolyl)-2'-((3,3-dimethyl-2-oxo-1-pyrrolidinyl)methyl)- (CAS 254737-87-6), a certified reference material (molecular formula C36H45N5O5S, MW 659.84 g/mol) for analytical method development and quality control.
Structurally, 254737-87-6 EEP77N970Y BMS-248360 UNII-EEP77N970Y (1,1'-Biphenyl)-2-sulfonamide, 4'-((2-butyl-4-oxo-1,3-diazaspiro(4.4)non-1-en-3-yl)methyl)-N-(3,4-dimethyl-5-isoxazolyl)-2'-((3,3-dimethyl-2-oxo-1-pyrrolidinyl)methyl)- (C36H45N5O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 659.84 g/mol, it falls into the 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.
