Chemical Structure
Description
The occurrence of Nitrosobenzene is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Nitrosobenzene (CAS 586-96-9), a certified reference material (molecular formula C6H5NO, MW 107.11 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, Nitrosobenzene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 107.11 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Nitrosobenzene 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.
