5-Isocyanato-1,3-dimethyl-1H-pyrazole CAS 785781-34-2

Description

As a certified reference material (CRM), 5-Isocyanato-1,3-dimethyl-1H-pyrazole 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.

5-Isocyanato-1,3-dimethyl-1H-pyrazole (CAS 785781-34-2), molecular formula C6H7N3O and molecular weight 137.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 5-Isocyanato-1,3-dimethyl-1H-pyrazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.14 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.
