4-(4-Bromo-1H-pyrazol-3-yl)pyridinehydrochloride CAS 1185103-91-6

Description

The occurrence of 4-(4-Bromo-1H-pyrazol-3-yl)pyridinehydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(4-Bromo-1H-pyrazol-3-yl)pyridinehydrochloride (CAS 1185103-91-6) is a high-purity analytical reference standard with the molecular formula C8H6BrN3HCl and a molecular weight of 260.52 g/mol.

The molecular framework of 4-(4-Bromo-1H-pyrazol-3-yl)pyridinehydrochloride (C8H6BrN3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 4-(4-Bromo-1H-pyrazol-3-yl)pyridinehydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
