Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(4-((Diphenylmethylene)amino)-3,5-diisopropylphenyl)boronicacid (CAS 849438-98-8), molecular formula C25H28BNO2 and molecular weight 385.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4-((Diphenylmethylene)amino)-3,5-diisopropylphenyl)boronicacid (C25H28BNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 385.31 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.
