N,N'-(6-Bromopyrido[2,3-d]pyrimidine-2,4-diyl)bis[2,2-dimethyl-propanamide (CAS 138609-27-5) is a high-purity analytical reference standard with the molecular formula C17H22BrN5O2 and a molecular weight of 408.29 g/mol.
Structurally, N,N'-(6-Bromopyrido[2,3-d]pyrimidine-2,4-diyl)bis[2,2-dimethyl-propanamide (C17H22BrN5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 408.29 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
