1-((5-Bromothiophen-2-yl)methyl)-4-methyl-1h-pyrazol-3-amine CAS 1341959-20-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-((5-Bromothiophen-2-yl)methyl)-4-methyl-1h-pyrazol-3-amine.

1-((5-Bromothiophen-2-yl)methyl)-4-methyl-1h-pyrazol-3-amine (CAS 1341959-20-3), molecular formula C9H10BrN3S and molecular weight 272.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution, 1-((5-Bromothiophen-2-yl)methyl)-4-methyl-1h-pyrazol-3-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-((5-Bromothiophen-2-yl)methyl)-4-methyl-1h-pyrazol-3-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.
