Description

The occurrence of N-(1'H,3H-[1,2'-biinden]-2-yl)acetamide 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.

N-(1'H,3H-[1,2'-biinden]-2-yl)acetamide (CAS 551930-59-7), molecular formula C20H17NO and molecular weight 287.36 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-(1'H,3H-[1,2'-biinden]-2-yl)acetamide (C20H17NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 287.36 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
