5-Chloro-3-(4-chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde CAS 55828-85-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-3-(4-chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde.

5-Chloro-3-(4-chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (CAS 55828-85-8), molecular formula C16H10Cl2N2O and molecular weight 317.17 g/mol, is a CATO reference standard with documented purity and traceability.

5-Chloro-3-(4-chlorophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (C16H10Cl2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
