Chemical Structure
Description
N-(4-Amino-6-chloropyrimidin-5-yl)formamide (CAS 7501-32-8) is a high-purity analytical reference standard with the molecular formula C5H5ClN4O and a molecular weight of 172.57 g/mol.
N-(4-Amino-6-chloropyrimidin-5-yl)formamide (C5H5ClN4O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), N-(4-Amino-6-chloropyrimidin-5-yl)formamide 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.
