Chemical Structure
Description
2-oxo-1,3-oxazinane-4-carboxylic acid (CAS 1543317-50-5) is a high-purity analytical reference standard with the molecular formula C5H7NO4 and a molecular weight of 145.11 g/mol.
The molecular framework of 2-oxo-1,3-oxazinane-4-carboxylic acid (C5H7NO4) 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.
As a certified reference material (CRM), 2-oxo-1,3-oxazinane-4-carboxylic 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.
