5-Amino-1-phenyl-1H-pyrazole-4-carbaldehyde CAS 62564-91-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Amino-1-phenyl-1H-pyrazole-4-carbaldehyde.

5-Amino-1-phenyl-1H-pyrazole-4-carbaldehyde (CAS 62564-91-4), molecular formula C10H9N3O and molecular weight 187.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Amino-1-phenyl-1H-pyrazole-4-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 5-Amino-1-phenyl-1H-pyrazole-4-carbaldehyde 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.
