1,3-diphenyl-4-pyrazolecarboxaldehyde 1,3-diphenylpyrazole-4-carbaldehyde 21487-45-6 A815414 CAS 21487-45-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-diphenyl-4-pyrazolecarboxaldehyde 1,3-diphenylpyrazole-4-carbaldehyde 21487-45-6 A815414.

1,3-diphenyl-4-pyrazolecarboxaldehyde 1,3-diphenylpyrazole-4-carbaldehyde 21487-45-6 A815414 (CAS 21487-45-6), molecular formula C16H28N2O and molecular weight 264.41 g/mol, is a CATO reference standard with documented purity and traceability.

1,3-diphenyl-4-pyrazolecarboxaldehyde 1,3-diphenylpyrazole-4-carbaldehyde 21487-45-6 A815414 (C16H28N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
