Description

172927-65-0 Sibrafiban [USAN:INN:BAN] ((1-(2-((4-(amino(hydroxyimino)methyl)benzoyl)amino)-1-oxopropyl)-4-piperidinyl)oxy)acetic acid ethyl ester Ro 48-3657 Sibrafiban Acetic acid, ((1-(2-((4-(amino(hydroxyimino)methyl)benzoyl)amino)-1-oxopropyl)-4-piperidinyl)oxy)-, ethyl ester, (S-(Z))- Ethyl (Z)-((1-(N-((p-hydroxyamidino)benzoyl)-L-alanyl)-4-piperidyl)oxy)acetate RO 48-3657/001 (CAS 172927-65-0) is a high-purity analytical reference standard with the molecular formula C20H28N4O6 and a molecular weight of 420.46 g/mol.

Based on its molecular formula C20H28N4O6, 172927-65-0 Sibrafiban [USAN:INN:BAN] ((1-(2-((4-(amino(hydroxyimino)methyl)benzoyl)amino)-1-oxopropyl)-4-piperidinyl)oxy)acetic acid ethyl ester Ro 48-3657 Sibrafiban Acetic acid, ((1-(2-((4-(amino(hydroxyimino)methyl)benzoyl)amino)-1-oxopropyl)-4-piperidinyl)oxy)-, ethyl ester, (S-(Z))- Ethyl (Z)-((1-(N-((p-hydroxyamidino)benzoyl)-L-alanyl)-4-piperidyl)oxy)acetate RO 48-3657/001 contains a flavonoid 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 420.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
