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-Chloro-5-hydrazino-1-methyl-1H-1,2,4-triazole (CAS 1255147-45-5) is a high-purity analytical reference standard with the molecular formula C3H6ClN5 and a molecular weight of 147.57 g/mol.
Structurally, 3-Chloro-5-hydrazino-1-methyl-1H-1,2,4-triazole (C3H6ClN5) 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 147.57 g/mol, it falls into the low-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-Chloro-5-hydrazino-1-methyl-1H-1,2,4-triazole 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.
