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 1,3-dimethyl-6-(3,4,5,6-tetrahydro-2H-azepin-7-ylamino)pyrimidine-2,4(1H,3H)-dione.
CATO supplies 1,3-dimethyl-6-(3,4,5,6-tetrahydro-2H-azepin-7-ylamino)pyrimidine-2,4(1H,3H)-dione (CAS 929975-78-0), a certified reference material (molecular formula C12H18N4O2, MW 250.30 g/mol) for analytical method development and quality control.
The molecular framework of 1,3-dimethyl-6-(3,4,5,6-tetrahydro-2H-azepin-7-ylamino)pyrimidine-2,4(1H,3H)-dione (C12H18N4O2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1,3-dimethyl-6-(3,4,5,6-tetrahydro-2H-azepin-7-ylamino)pyrimidine-2,4(1H,3H)-dione 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.
