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 6-chloro-2-N-methyl-5-nitrosopyrimidine-2,4-diamine.
6-chloro-2-N-methyl-5-nitrosopyrimidine-2,4-diamine (CAS 1803584-80-6) is a high-purity analytical reference standard with the molecular formula C5H6ClN5O and a molecular weight of 187.59 g/mol.
Structurally, 6-chloro-2-N-methyl-5-nitrosopyrimidine-2,4-diamine (C5H6ClN5O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 187.59 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 6-chloro-2-N-methyl-5-nitrosopyrimidine-2,4-diamine 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.
