Description
[5-cyano-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-naphthyl] 2,2-dimethylpropanoate (CAS 2757096-99-2), molecular formula C22H36BNO4 and molecular weight 389.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, [5-cyano-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-naphthyl] 2,2-dimethylpropanoate (C22H36BNO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 389.34 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
