Chemical Structure
Description
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.
3-(Chloromethyl)-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazole hydrochloride (CAS 1820685-05-9), molecular formula C6H8ClN3HCl and molecular weight 194.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(Chloromethyl)-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazole hydrochloride (C6H8ClN3HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 194.06 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).
As a certified reference material (CRM), 3-(Chloromethyl)-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazole hydrochloride 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.
