Chemical Structure
Description
As a certified reference material (CRM), 5-Carbamoylbarbituric acid 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.
CATO supplies 5-Carbamoylbarbituric acid (CAS 56032-78-1), a certified reference material (molecular formula C5H5N3O4, MW 171.11 g/mol) for analytical method development and quality control.
The molecular framework of 5-Carbamoylbarbituric acid (C5H5N3O4) is characterized by a carbohydrate-derived structure, an amide group. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
