Pharmaceutical Testing Reference Mterials

Pharmaceutical Reference Materials (PRMs) refer to substances with defined characteristic values used for calibrating instruments, evaluating measurement methods, or assigning values to tested pharmaceuticals in physical/chemical tests and biological assays specified by pharmacopoeial standards. These include reference standards, comparators, herbal reference materials, and reference preparations.

Hengyuan Fine Chemical specializes in providing cost-effective reference material solutions for pharmaceutical quality control, encompassing:

• Drug testing reference standards
• Pharmaceutical impurity reference standards
• NIFDC-certified reference materials
• Chemical analysis reference standards
• Traditional Chinese Medicine (TCM) analytical standards
• TCM reference standards
• Herbal blank matrices for pesticide residue testing
• Bio-peptide reference standards

All products under our PCL brand comply with both national standards and international guidelines. Our accreditations include:

• CNAS certification (China National Accreditation Service for Conformity Assessment)
• ISO 17034:2016 certification for reference material producers
• ISO 9001:2015 quality management system certification We implement a comprehensive quality management system supported by Certificates of Analysis (COA), ensuring high purity (>98%), batch-to-batch consistency, and full traceability. Our solutions are widely applied in pharmaceutical R&D, QC testing, and analytical verification to enhance testing accuracy and operational efficiency.

Through our vertically integrated business model (R&D-production-sales), we eliminate intermediaries to deliver:

 ✓ Bulk supply capacities for routine QC needs 

✓ Custom synthesis services for specialized compounds 

✓ 30-50% cost reduction versus market averages 

✓ Streamlined procurement workflows 

This dual approach establishes economically optimized yet reliable quality control frameworks for clients across the pharmaceutical value chain.
