Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methylpyrimidine-5-carboxylic acid hydrate.
2-Methylpyrimidine-5-carboxylic acid hydrate (CAS 1314670-28-4) is a high-purity analytical reference standard with the molecular formula C6H6N2O2H2O and a molecular weight of 156.14 g/mol.
The molecular framework of 2-Methylpyrimidine-5-carboxylic acid hydrate (C6H6N2O2H2O) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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-Methylpyrimidine-5-carboxylic acid hydrate 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.
