For professionals in the chemical, pharmaceutical, and cosmetic industries, the successful procurement of specialized compounds like 5-Chloro-2-(methylamino)benzophenone (CAS 1022-13-5) hinges on meticulous planning and supplier verification. This guide outlines a buyer's checklist to ensure a smooth and effective acquisition process for this important fine chemical.

1. Verify Purity and Specifications: The first and most critical step is to confirm the purity of 5-Chloro-2-(methylamino)benzophenone. Typically supplied as a white powder, a minimum purity of 98% is often required for pharmaceutical and cosmetic applications. Always request a Certificate of Analysis (CoA) that details lot-specific purity, along with other relevant analytical data such as spectroscopic information or impurity profiles. Understanding the molecular formula (C14H12ClNO) and molecular weight (245.71) is also fundamental.

2. Assess Supplier Reliability: Identify manufacturers or suppliers with a proven track record. Look for companies that demonstrate robust quality management systems, adherence to industry standards, and transparent manufacturing processes. Direct manufacturers, especially those in established chemical production hubs like China, often offer greater reliability and competitive pricing. Investigate their production capacity and ability to meet your projected demand.

3. Request Detailed Quotes and Samples: Before committing to a purchase, obtain detailed price quotations that clearly outline the cost per unit, minimum order quantities (MOQ), and any potential bulk discounts. Crucially, request product samples for in-house testing and evaluation. This step is indispensable for validating that the supplied chemical meets your exact requirements and performs as expected in your applications.

4. Clarify Logistics and Payment Terms: Understand the shipping options and associated costs. Standard Incoterms like FOB (Free On Board), CFR (Cost and Freight), or CIF (Cost, Insurance, and Freight) should be clearly defined. Discuss payment terms (e.g., L/C, T/T, PayPal) and lead times for order fulfillment and delivery. Reliable communication regarding shipping status is also a key indicator of a dependable supplier.

5. Evaluate Technical Support and Documentation: A good supplier will offer responsive technical support to address any queries regarding the product's properties, handling, or applications. Ensure they can provide necessary documentation, such as Safety Data Sheets (SDS), which are crucial for safe handling and regulatory compliance.

By following this checklist, procurement professionals can confidently source 5-Chloro-2-(methylamino)benzophenone (CAS 1022-13-5) from reputable manufacturers, ensuring the quality and consistency necessary for their critical industrial processes.
