Chemical Structure
Description
As a certified reference material (CRM), 1-(5-Chloropyrimidin-2-yl)ethan-1-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.
1-(5-Chloropyrimidin-2-yl)ethan-1-amine (CAS 944902-32-3) is a high-purity analytical reference standard with the molecular formula C6H8ClN3 and a molecular weight of 157.60 g/mol.
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 1-(5-Chloropyrimidin-2-yl)ethan-1-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 157.60 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
