The molecular framework of 2,5-Dimethoxy-4-(4-nitrophenylazo)benzenediazonium chloride zinc double salt 2,5-Dimethoxy-4-([4-nitrophenyl]azo)benzenediazonium chloride hemi(zinc chloride) salt 4-Amino-2,5-dimethoxy-4 inverted exclamation marka-nitroazobenzene diazotated zinc double salt 64071-86-9 Azoic Diazo No. 38 Brentamine fast black K salt Fast Black K Salt hemi(zinc chloride) salt Fast Black K salt (C14H24N5O4Cl2ZnCl) is characterized by a salt form, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
