Description

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.

CATO supplies 133737-32-3 38VAG2SA33 Pagoclone Pagoclone [USAN:INN] 1H-Isoindol-1-one, 2-(7-chloro-1,8-naphthyridin-2-yl)-2,3-dihydro-3-(5-methyl-2-oxohexyl)-, (+)- (+)-RP 59037 IP 456 RP 62955 (+)-2-(7-Chloro-1,8-naphthyridin-2-yl)-3-(5-methyl-2-oxohexyl)phthalimidine UNII-38VAG2SA33 Bextra (CAS 133737-32-3), a certified reference material (molecular formula C23H22ClN3O2, MW 407.89 g/mol) for analytical method development and quality control.

133737-32-3 38VAG2SA33 Pagoclone Pagoclone [USAN:INN] 1H-Isoindol-1-one, 2-(7-chloro-1,8-naphthyridin-2-yl)-2,3-dihydro-3-(5-methyl-2-oxohexyl)-, (+)- (+)-RP 59037 IP 456 RP 62955 (+)-2-(7-Chloro-1,8-naphthyridin-2-yl)-3-(5-methyl-2-oxohexyl)phthalimidine UNII-38VAG2SA33 Bextra (C23H22ClN3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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).
