Ertapenem Side Chain is a synthetic organic intermediate with the chemical name 3-[(2S,4S)-4-mercaptopyrrolidine-2-carboxamido]benzoic acid hydrochloride, CAS No. 219909-83-8. It is a white to off-white crystalline powder used in the semi-synthesis of the carbapenem antibiotic Ertapenem. The compound is manufactured under GMP conditions and is subject to strict purity controls to meet pharmaceutical-grade standards.
The material has a melting point of 212°C and a purity of 98.786% as confirmed by HPLC assay. Moisture content is below 0.50%, consistent with typical specifications for sensitive API intermediates. The compound is stable under dry, cool conditions but degrades in the presence of moisture or strong acids. Standard packaging is double-sealed HDPE bags inside airtight drums to prevent hygroscopic absorption.
This intermediate is purchased by pharmaceutical manufacturers producing broad-spectrum antibiotics, particularly those sourcing carbapenem precursors for bulk drug substance synthesis. Buyers typically require a Certificate of Analysis with HPLC, NMR, and chiral purity data. Trade is conducted in bulk quantities of 1 kg to 25 kg, with lead times of 20 to 30 days. Incoterms are usually EXW Hangzhou or FOB Shanghai.

Before ordering, verify the Certificate of Analysis includes HPLC chromatograms, moisture content by Karl Fischer, and melting point confirmation. Request a sample for purity validation and check for any signs of caking or discoloration, which may indicate degradation. Confirm the supplier uses sealed, moisture-barrier packaging consistent with ICH guidelines.
Lead time is typically 20 to 30 days from order confirmation. Incoterms are usually EXW Hangzhou or FOB Shanghai; clarify who handles export documentation and customs clearance. Payment is typically 50% advance and 50% against copy of shipping documents. Avoid 100% prepayment without third-party inspection.
Upon delivery, inspect the drum for integrity and verify the batch number matches the COA. Perform a quick moisture test with a hygrometer. Retain a sample for retesting and request a second sample from the same batch for independent lab analysis. Ensure the supplier provides a safety data sheet compliant with GHS and local regulations.
