Ethyl D-(-)-pyroglutamate is the ethyl ester of the D‑enantiomer of pyroglutamic acid, used as a chiral building block in synthesis. Wuhan Yuan Cheng GongChuang Technology Co.Ltd lists the material with a CAS number 68766-96-1, a molecular weight of 157.1671 g mol⁻¹ and an assay of 97 % purity. The compound is supplied in 1 kg bags that are sealed under nitrogen to protect its stereochemical integrity. Its molecular formula is C7H11NO3, and it appears as a colourless solid at room temperature.
In the chemicals market, D‑ethyl pyroglutamate is typically stored at 2‑8 °C under inert atmosphere to minimise racemisation (typical). Moisture content for similar esters is usually kept below 0.2 % (typical) to avoid hydrolysis. The product is reported to be soluble in polar aprotic solvents such as dimethylformamide and dimethyl sulfoxide, a characteristic shared by many amino‑acid derivatives (typical). While the listing does not provide a melting point, related compounds melt between 120‑130 °C (typical), which can be used as a reference for quality checks.
The ester is employed in asymmetric synthesis routes, peptide coupling reactions and the development of central‑nervous‑system drug candidates. Research laboratories and contract manufacturing organisations commonly source it for scale‑up projects. The supplier indicates that shipments can be arranged under FOB or CIF terms, and buyers should verify packaging, required certifications and payment conditions directly with the company.

Sourcing Ethyl D-(-)-pyroglutamate from Wuhan Yuan Cheng GongChuang Technology Co.Ltd - China Import Guide
Prior to ordering, importers should obtain a current certificate of analysis, safety data sheet and any relevant chiral‑purity test results to confirm the 97 % assay and D‑configuration. Verify that the 1 kg nitrogen‑sealed bags meet your handling requirements and that the packaging labels match the agreed specifications.
Logistics for this product are commonly arranged under FOB or CIF terms, but the exact incoterm, port of loading and expected lead time must be clarified with Wuhan Yuan Cheng GongChuang Technology Co.Ltd. Discuss freight options, customs documentation and preferred payment methods such as L/C or advance payment before the shipment is scheduled.
Quality control can be strengthened by commissioning a third‑party laboratory to test assay, optical rotation and moisture content on the received batch. Arrange a pre‑shipment inspection to check bag integrity and nitrogen purge. Retaining all test reports and certificates will facilitate customs clearance and ensure the material meets your downstream manufacturing standards.
