Chemical Structure

Nusinersen CAS 1258984-36-9 chemical structure

Description

The occurrence of Nusinersen is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Nusinersen (CAS 1258984-36-9), molecular formula C234H340N61O128P17S17 and molecular weight 7127.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Nusinersen (C234H340N61O128P17S17) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 95.5, corresponding to approximately 95 ring(s) or double-bond equivalent(s). With a molecular weight of 7127.19 g/mol, it falls into the 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.

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.
