6,7-Dimethoxy-12,16,18,25-tetraazahexacyclo[12.11.0.0^{3,12}.0^{4,9}.0^{17,25}.0^{19,24}]pentacosa-1(14),4(9),5,7,15,17,19(24),20,22-nonaen-13-one CAS 685107-15-7

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 6,7-Dimethoxy-12,16,18,25-tetraazahexacyclo[12.11.0.0^{3,12}.0^{4,9}.0^{17,25}.0^{19,24}]pentacosa-1(14),4(9),5,7,15,17,19(24),20,22-nonaen-13-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 400.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

6,7-Dimethoxy-12,16,18,25-tetraazahexacyclo[12.11.0.0^{3,12}.0^{4,9}.0^{17,25}.0^{19,24}]pentacosa-1(14),4(9),5,7,15,17,19(24),20,22-nonaen-13-one (CAS 685107-15-7) is a high-purity analytical reference standard with the molecular formula C23H20N4O3 and a molecular weight of 400.43 g/mol.

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.

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.
