Product Code: C138002
English Name: Chlortalidone Impurity 2
English Alias: 2-(3-chlorobenzoyl)benzoic acid
CAS No.：13450-37-8
Molecular Formula: C₁₄H₉ClO₃
Molecular Weight: 260.67
High Purity & Structural Confirmation: HPLC ≥99.0%, validated by NMR and HRMS.
Stability: Stable for 24 months at -20℃, with <0.3% degradation in methanol.
Regulatory Compliance: Meets EP/USP standards for diuretic impurity control.
Impurity Detection: Quantifies Impurity 2 in Chlortalidone formulations via LC-MS.
Synthesis Monitoring: Tracks 3-chlorobenzoyl residue during ring closure reactions.
Method Validation: Supports specificity testing for chromatographic methods.
This impurity forms from isomeric chlorobenzoyl reagents in Chlortalidone synthesis. Controlling positional isomers is critical for drug quality.
Detection: HPLC with C18 column (5μm) and gradient elution; LOD: 0.05 μg/mL.
Formation Mechanism: Results from ortho/meta chlorination selectivity; using catalyzed chlorination reduces meta-isomer by 65%.
Safety Evaluation: Acute toxicity tests show no adverse effects; chronic studies in progress.
