3-Amino-4-hydroxybenzonitrile CAS 14543-43-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-4-hydroxybenzonitrile.

CATO supplies 3-Amino-4-hydroxybenzonitrile (CAS 14543-43-2), a certified reference material (molecular formula C7H6N2O, MW 134.14 g/mol) for analytical method development and quality control.

Structurally, 3-Amino-4-hydroxybenzonitrile (C7H6N2O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 134.14 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 3-Amino-4-hydroxybenzonitrile 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.
