1H-Indole-2, 5,7-dichloro- 5,3-dione 5,7-Dichloroisatin 6374-92-1 Indole-2, 5,7-dichloro- Isatin,7-dichloro- MLS002639083 NSC-26045 NSC26045 CAS 6374-92-1

Description

The occurrence of 1H-Indole-2, 5,7-dichloro- 5,3-dione 5,7-Dichloroisatin 6374-92-1 Indole-2, 5,7-dichloro- Isatin,7-dichloro- MLS002639083 NSC-26045 NSC26045 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1H-Indole-2, 5,7-dichloro- 5,3-dione 5,7-Dichloroisatin 6374-92-1 Indole-2, 5,7-dichloro- Isatin,7-dichloro- MLS002639083 NSC-26045 NSC26045 (CAS 6374-92-1), molecular formula C8H9Cl2NO2 and molecular weight 222.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1H-Indole-2, 5,7-dichloro- 5,3-dione 5,7-Dichloroisatin 6374-92-1 Indole-2, 5,7-dichloro- Isatin,7-dichloro- MLS002639083 NSC-26045 NSC26045 (C8H9Cl2NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
