Phloroglucinol

Buyers must prioritize purity levels, typically requiring ≥99% for pharmaceutical or analytical grades. Ensure the product complies with international pharmacopoeia standards such as USP (United States Pharmacopeia), EP (European Pharmacopoeia), or BP (British Pharmacopoeia). Key parameters to verify include melting point (217-220°C), loss on drying (≤1.0%), and heavy metal content (≤10ppm). Always request a Certificate of Analysis (COA) and Method of Analysis (MOA) from the supplier to validate these metrics.

Phloroglucinol is a versatile chemical intermediate. In the pharmaceutical industry, it is used as an antispasmodic agent for treating gastrointestinal and biliary tract disorders. In the textile and printing industries, it serves as a coupling agent for azo dyes and a constituent in diazo-type printing and photocopying. Additionally, it is utilized in analytical chemistry as a reagent for detecting pentoses and lignin. Buyers should specify their intended application to ensure the particle size and solubility meet their process requirements.

As a chemical substance, the supplier must provide a comprehensive Safety Data Sheet (SDS/MSDS) compliant with GHS (Globally Harmonized System). For pharmaceutical applications, the manufacturer should ideally hold GMP (Good Manufacturing Practice) certification and a Drug Master File (DMF) number. For European market entry, REACH registration is essential. Ensure the supplier is ISO 9001 certified to guarantee consistent batch-to-batch quality management.

Phloroglucinol is sensitive to light and moisture. It must be packed in fiber drums with double-layer PE bags or amber glass containers for smaller quantities. Ensure the packaging is UN-certified for chemical transport. During shipping, it should be stored in a cool, dry, and well-ventilated area away from strong oxidizing agents. For cross-border logistics to countries like the US or EU, verify the HS Code (typically 2907.29) to determine accurate import duties.

To ensure security, use Trade Assurance services provided by platforms like Made-in-China.com to protect payments until delivery is confirmed. Conduct factory audits or hire third-party inspection agencies (like SGS or Intertek) to perform Pre-Shipment Inspection (PSI). This verifies that the quantity and quality match the Proforma Invoice. Avoid suppliers who refuse to provide free samples for lab testing or those who lack a verifiable business license.

Price for Phloroglucinol is highly dependent on raw material costs (e.g., resorcinol) and order volume. For orders exceeding 500kg, buyers can typically negotiate a 10-15% discount. It is recommended to use FOB (Free On Board) terms to maintain control over shipping costs, or CIF (Cost, Insurance, and Freight) if you prefer the supplier to handle the risk until the port of destination. Always include a quality claim clause in the contract, allowing for returns or refunds if the third-party test results fail to meet the agreed COA.
