The molecular framework of V561V90BG2 7601-90-3 UNII-V561V90BG2 Perchloric acid, not >50% acid, by mass Perchloric acid, >50% but not >72% acid, by mass Perchloric acid, >72% acid by mass Perchloric acid Perchloric acid, >72% acid by mass [Forbidden] Perchloric acid, >50% but not >72% acid, by mass [UN1873] [Oxidizer, Corrosive] Perchloric acid, not >50% acid, by mass [UN1802] [Corrosive, Oxidizer] UN1802 UN1873 EINECS 231-512-4 HSDB 1140 EC 231-512-4 (HClO4) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
