(1R,2S,3R,4S)-1,4-diamino-6-bromo-1,2,3,4-tetrahydronaphthalene-2,3-diol CAS 1998128-33-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 273.13 g/mol gives (1R,2S,3R,4S)-1,4-diamino-6-bromo-1,2,3,4-tetrahydronaphthalene-2,3-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1R,2S,3R,4S)-1,4-diamino-6-bromo-1,2,3,4-tetrahydronaphthalene-2,3-diol (CAS 1998128-33-8) is a high-purity analytical reference standard with the molecular formula C10H13BrN2O2 and a molecular weight of 273.13 g/mol.

(1R,2S,3R,4S)-1,4-diamino-6-bromo-1,2,3,4-tetrahydronaphthalene-2,3-diol (C10H13BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 (1R,2S,3R,4S)-1,4-diamino-6-bromo-1,2,3,4-tetrahydronaphthalene-2,3-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.
