Description

The occurrence of 95EG3HGG1P 491-30-5 Isocarbostyril 1-Hydroxyisoquinoline Isocarbostyril (VAN) (8CI) 1(2H)-Isoquinolinone AI3-62131 EINECS 207-732-1 1-Isoquinolinol Isoquinolin-1-one 1(2H)-Isoquinolone NSC 27273 UNII-95EG3HGG1P is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

95EG3HGG1P 491-30-5 Isocarbostyril 1-Hydroxyisoquinoline Isocarbostyril (VAN) (8CI) 1(2H)-Isoquinolinone AI3-62131 EINECS 207-732-1 1-Isoquinolinol Isoquinolin-1-one 1(2H)-Isoquinolone NSC 27273 UNII-95EG3HGG1P (CAS 491-30-5) is a high-purity analytical reference standard with the molecular formula C9H17NOC9H13NO and a molecular weight of 306.45 g/mol.

95EG3HGG1P 491-30-5 Isocarbostyril 1-Hydroxyisoquinoline Isocarbostyril (VAN) (8CI) 1(2H)-Isoquinolinone AI3-62131 EINECS 207-732-1 1-Isoquinolinol Isoquinolin-1-one 1(2H)-Isoquinolone NSC 27273 UNII-95EG3HGG1P (C9H17NOC9H13NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
