Chemical Structure
Description
The occurrence of 3-Hydroxybiuret is closely related to an amino-acid-derived structure, an amide group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Hydroxybiuret (CAS 4381-13-9) is a high-purity analytical reference standard with the molecular formula C2H5N3O3 and a molecular weight of 119.08 g/mol.
Based on its molecular formula C2H5N3O3, 3-Hydroxybiuret contains an amino-acid-derived structure, an amide group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 119.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 3-Hydroxybiuret 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.
