3-Butyl-5-chloro-1-phenyl-1H-pyrazole-4-carbaldehyde CAS 1354936-89-2

Description

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

3-Butyl-5-chloro-1-phenyl-1H-pyrazole-4-carbaldehyde (CAS 1354936-89-2), molecular formula C14H15ClN2O and molecular weight 262.73 g/mol, is a CATO reference standard with documented purity and traceability.

3-Butyl-5-chloro-1-phenyl-1H-pyrazole-4-carbaldehyde (C14H15ClN2O) 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. 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.

CATO manufactures 3-Butyl-5-chloro-1-phenyl-1H-pyrazole-4-carbaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
