Chemical Structure

4-Hydroxybenzimidamide CAS 15535-98-5 chemical structure

Description

As a certified reference material (CRM), 4-Hydroxybenzimidamide 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.

4-Hydroxybenzimidamide (CAS 15535-98-5), molecular formula C7H8N2O and molecular weight 136.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Hydroxybenzimidamide (C7H8N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.

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.
