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-(2-Chloroethyl)-2,3-dihydroimidazo[1,2-c]pyrimidine-5(1H)-thione.
1-(2-Chloroethyl)-2,3-dihydroimidazo[1,2-c]pyrimidine-5(1H)-thione (CAS 7151-75-9), molecular formula C8H10ClN3S and molecular weight 215.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(2-Chloroethyl)-2,3-dihydroimidazo[1,2-c]pyrimidine-5(1H)-thione (C8H10ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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 215.70 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), 1-(2-Chloroethyl)-2,3-dihydroimidazo[1,2-c]pyrimidine-5(1H)-thione 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.
