Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-(Benzo[d][1,3]dioxol-5-yl)thiazol-2-yl)-3-methyl-1h-pyrazol-5-amine.
1-(4-(Benzo[d][1,3]dioxol-5-yl)thiazol-2-yl)-3-methyl-1h-pyrazol-5-amine (CAS 1171918-18-5), molecular formula C14H12N4O2S and molecular weight 300.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(4-(Benzo[d][1,3]dioxol-5-yl)thiazol-2-yl)-3-methyl-1h-pyrazol-5-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.34 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), 1-(4-(Benzo[d][1,3]dioxol-5-yl)thiazol-2-yl)-3-methyl-1h-pyrazol-5-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.
