Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3-(4-Chlorophenyl)-1-phenyl-1h-pyrazol-4-yl)acrylic acid.
3-(3-(4-Chlorophenyl)-1-phenyl-1h-pyrazol-4-yl)acrylic acid (CAS 55432-14-9) is a high-purity analytical reference standard with the molecular formula C18H13ClN2O2 and a molecular weight of 324.76 g/mol.
Structurally, 3-(3-(4-Chlorophenyl)-1-phenyl-1h-pyrazol-4-yl)acrylic acid (C18H13ClN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 324.76 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 3-(3-(4-Chlorophenyl)-1-phenyl-1h-pyrazol-4-yl)acrylic acid 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.
