Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,4aR,4bS,8R,8aS,9S,10aR,E)-7-(2-(2-(Dimethylamino)ethoxy)-2-oxoethylidene)-9-hydroxy-1,1,4a,8-tetramethyltetradecahydrophenanthren-2-yl 3-hydroxybutanoate hydrochloride.
(2S,4aR,4bS,8R,8aS,9S,10aR,E)-7-(2-(2-(Dimethylamino)ethoxy)-2-oxoethylidene)-9-hydroxy-1,1,4a,8-tetramethyltetradecahydrophenanthren-2-yl 3-hydroxybutanoate hydrochloride (CAS 63907-37-9) is a high-purity analytical reference standard with the molecular formula C28H47NO6HCl and a molecular weight of 530.14 g/mol.
The molecular framework of (2S,4aR,4bS,8R,8aS,9S,10aR,E)-7-(2-(2-(Dimethylamino)ethoxy)-2-oxoethylidene)-9-hydroxy-1,1,4a,8-tetramethyltetradecahydrophenanthren-2-yl 3-hydroxybutanoate hydrochloride (C28H47NO6HCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
