Chemical Identity & Classification

4-CL-PVP Crystals carry CAS identifiers linked to 4′-Chloro-α-pyrrolidinovalerophenone, with molecular formula C15H20ClNO and molecular weight 265.78 g/mol. Common synonyms include 4-Chloro-alpha-PVP, 4Cl-PVP, and 1-(4-chlorophenyl)-2-(1-pyrrolidinyl)-pentan-1-one. Classified as a synthetic pyrrolidinophenone reference material and analytical reagent.

These identifiers facilitate precise documentation in research protocols, positioning it as a standard for impurity profiling and structural elucidation in forensic and pharmaceutical analysis.

Chemical & Physical Characteristics

4-CL-PVP Crystals appear as a white to off-white crystalline solid, exhibiting solubility in polar organic solvents such as DMSO and ethanol, with limited aqueous solubility. The compound maintains stability under inert atmospheres, suitable for standard lab handling at ambient temperatures. Physical properties include a calculated logP supporting lipophilic interactions in analytical separations.

Uniform crystal morphology aids in reproducible weighing and dissolution for microscale experiments. Observable traits align with pyrrolidinophenone class expectations, free from discoloration or agglomeration.​

Purity & Analytical Verification

All 4-CL-PVP Crystals batches exceed 98% purity, validated through high-performance liquid chromatography (HPLC), gas chromatography (GC), nuclear magnetic resonance (NMR), and liquid chromatography-mass spectrometry (LC-MS). Certificate of Analysis (COA) provided per lot details residual solvents and impurities below 0.5%.

Orthogonal analytical techniques confirm monoisotopic mass at 265.123 Da, essential for mass spectrometry reference standards. COA accessibility ensures traceability for peer-reviewed publications.​

Quality Control & Batch Integrity

Batch-controlled synthesis employs traceable raw materials, with each lot subjected to in-process monitoring and final QC via standardized protocols. Lot-specific documentation includes synthesis logs, purity chromatograms, and retention samples for up to five years. Third-party auditing available for high-volume orders.

This framework minimizes inter-batch variability, supporting long-term research continuity. Records integrate seamlessly with laboratory information management systems (LIMS).​

Safety, Handling & Laboratory Precautions

Process 4-CL-PVP Crystals in certified fume hoods by personnel trained in handling synthetic organic reagents, using PPE such as nitrile gloves, safety goggles, and respiratory protection if aerosols are possible. Employ secondary containment and spill kits in designated areas. Refer to accompanying Material Safety Data Sheet (MSDS/SDS) for detailed protocols.

Decontaminate equipment post-use and dispose via approved hazardous waste streams. Standard precautions mirror those for related cathinone analogs.​

Packaging, Labeling & Storage

Packaged in amber glass vials with PTFE-lined septa and tamper-evident seals to shield from light and humidity. Labels feature CAS reference, batch code, purity declaration, and GHS-compliant hazard symbols. Store at -20°C in a desiccator to retain integrity beyond 24 months.

Secure overpackaging facilitates safe transit while maintaining discretion. Conditions prevent hydrolytic or oxidative degradation.​

Intended Research Use & Market Positioning

4-CL-PVP Crystals target analytical chemistry, reference calibration in LC-MS/GC-MS, forensic method validation, and industrial R&D for pharmaceutical impurities. Educational institutions employ it in advanced organic chemistry curricula. Marketed as a high-purity, economical option for global labs requiring pyrrolidinophenone standards.
