Description

CATO manufactures 1,4-Bis(4-bromophenyl)-1H-pyrazol-5-amine 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.

1,4-Bis(4-bromophenyl)-1H-pyrazol-5-amine (CAS 1202028-75-8), molecular formula C15H11Br2N3 and molecular weight 393.08 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,4-Bis(4-bromophenyl)-1H-pyrazol-5-amine (C15H11Br2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 393.08 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
