4-(2-Bromo-4-ethylphenyl)thiosemicarbazide (CAS 1263377-22-5), molecular formula C9H12BrN3S and molecular weight 274.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2-Bromo-4-ethylphenyl)thiosemicarbazide (C9H12BrN3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine 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.
