4-(Hydroxyimino)cyclohexa-2,5-dien-1-one CAS 637-62-7

Description

Compared with other compounds in its class, the molecular weight of 123.11 g/mol gives 4-(Hydroxyimino)cyclohexa-2,5-dien-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(Hydroxyimino)cyclohexa-2,5-dien-1-one (CAS 637-62-7), a certified reference material (molecular formula C6H5NO2, MW 123.11 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-(Hydroxyimino)cyclohexa-2,5-dien-1-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
