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-Chloro-4-hydrazinyl-5-methoxypyrimidine.
2-Chloro-4-hydrazinyl-5-methoxypyrimidine (CAS 98021-95-5), molecular formula C5H7ClN4O and molecular weight 174.59 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-4-hydrazinyl-5-methoxypyrimidine (C5H7ClN4O) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
