Chemical Structure
Description
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 supplies 1-(3-Chlorophenyl)-N3,N3,N5,N5-tetramethyl-1H-1,2,4-triazole-3,5-diamine (CAS 251307-18-3), a certified reference material (molecular formula C12H16ClN5, MW 265.74 g/mol) for analytical method development and quality control.
1-(3-Chlorophenyl)-N3,N3,N5,N5-tetramethyl-1H-1,2,4-triazole-3,5-diamine (C12H16ClN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
CATO manufactures 1-(3-Chlorophenyl)-N3,N3,N5,N5-tetramethyl-1H-1,2,4-triazole-3,5-diamine 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.
