Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Chloromethyl)pyrimidin-5-amine (CAS 1240598-93-9), molecular formula C5H6ClN3 and molecular weight 143.57 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, 2-(Chloromethyl)pyrimidin-5-amine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), 2-(Chloromethyl)pyrimidin-5-amine 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.
