Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1s,9s,13s,14r,16r,17s)-4-(2-hydroxyethyl)-13,17-dimethyl-11-azapentacyclo[12.3.1.01,5.09,17.011,16]octadec-4-ene-6,18-dione 881388-88-1.

(1s,9s,13s,14r,16r,17s)-4-(2-hydroxyethyl)-13,17-dimethyl-11-azapentacyclo[12.3.1.01,5.09,17.011,16]octadec-4-ene-6,18-dione 881388-88-1 (CAS 881388-88-1) is a high-purity analytical reference standard with the molecular formula C21H29NO3 and a molecular weight of 343.46 g/mol.

Based on its molecular formula C21H29NO3, (1s,9s,13s,14r,16r,17s)-4-(2-hydroxyethyl)-13,17-dimethyl-11-azapentacyclo[12.3.1.01,5.09,17.011,16]octadec-4-ene-6,18-dione 881388-88-1 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 343.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
