4-methyl-1-(1,2,3,4-tetrahydronaphthalen-1-yl)-1H-pyrazol-5-amine hydrochloride CAS 1235438-77-3

Description

4-methyl-1-(1,2,3,4-tetrahydronaphthalen-1-yl)-1H-pyrazol-5-amine hydrochloride (CAS 1235438-77-3), molecular formula C14H17N3HCl and molecular weight 263.77 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-methyl-1-(1,2,3,4-tetrahydronaphthalen-1-yl)-1H-pyrazol-5-amine hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 263.77 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.

As a certified reference material (CRM), 4-methyl-1-(1,2,3,4-tetrahydronaphthalen-1-yl)-1H-pyrazol-5-amine 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.
