Description

The occurrence of 2-(9H-fluoren-9-ylmethoxycarbonylamino)-2-methyl-dec-9-enoic acid 2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-2-methyl-9-decenoic acid 945212-26-0 A844989 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(9H-fluoren-9-ylmethoxycarbonylamino)-2-methyl-dec-9-enoic acid 2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-2-methyl-9-decenoic acid 945212-26-0 A844989 (CAS 945212-26-0), molecular formula C26H31NO4 and molecular weight 421.53 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(9H-fluoren-9-ylmethoxycarbonylamino)-2-methyl-dec-9-enoic acid 2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-2-methyl-9-decenoic acid 945212-26-0 A844989 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 421.53 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).

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.
