Chemical Structure

N-Hydroxy-4-methylaniline CAS 623-10-9 chemical structure

Description

CATO supplies N-Hydroxy-4-methylaniline (CAS 623-10-9), a certified reference material (molecular formula C7H9NO, MW 123.15 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, N-Hydroxy-4-methylaniline is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), N-Hydroxy-4-methylaniline 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.
