Description
Compared with other compounds in its class, the molecular weight of 159.57 g/mol gives 4-Amino-6-chlorobenzene-1,3-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Amino-6-chlorobenzene-1,3-diol (CAS 412307-65-4) is a high-purity analytical reference standard with the molecular formula C6H6ClNO2 and a molecular weight of 159.57 g/mol.
The molecular framework of 4-Amino-6-chlorobenzene-1,3-diol (C6H6ClNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
CATO manufactures 4-Amino-6-chlorobenzene-1,3-diol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
