N-Methyl SB 277011 CAS 1159977-51-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Methyl SB 277011.

N-Methyl SB 277011 (CAS 1159977-51-1), molecular formula C29H32N4O and molecular weight 452.59 g/mol, is a CATO reference standard with documented purity and traceability.

N-Methyl SB 277011 (C29H32N4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
