D, l-selenomethionine
D, l-selenomethionine is an organic selenium compound with the molecular formula C5H11NO2Se and a molecular weight of 196.11 g/mol. It appears as a white to off-white crystalline powder and is synthesized to contain a minimum of 98% purity by HPLC. This compound is not a racemic mixture but a defined stereochemical form used in nutritional applications where bioavailability matters.
The compound is typically produced via microbial fermentation or chemical synthesis with chiral resolution, resulting in a product that meets USP and EP monograph standards for selenium amino acid derivatives. Typical moisture content is below 0.5%, and heavy metal impurities are controlled to below 10 ppm. It is stable under dry, cool conditions and is often handled under nitrogen during packaging to prevent oxidation.
This material is primarily purchased by manufacturers of dietary supplements, functional foods, and animal feed formulations requiring bioavailable selenium. Buyers commonly use it to fortify products targeting immune support, thyroid health, and antioxidant defense. Packaging is usually in 25 kg HDPE drums with inner food-grade polyethylene liners. Trade terms typically include FOB Shanghai or CIF destination, with standard lead times of 10 to 15 days after order confirmation.

Sourcing D, l-selenomethionine from Hangzhou King Techina Technology Co., Ltd. - China Import Guide
Before placing an order, verify the Certificate of Analysis for each batch, ensuring it includes HPLC purity, moisture content, heavy metal limits, and identity confirmation via IR or NMR. Request the method of synthesis and whether the compound is racemic or enantiomerically enriched. Confirm the supplier's internal QC protocols and whether they perform third-party testing. Do not accept generic statements like 'meets industry standards' without data.
Confirm the Incoterms offered - typically FOB Shanghai or CIF destination - and ensure the packaging complies with your country's import regulations for food-grade selenium. Lead times are generally 10 to 15 days after payment, but production scheduling may vary. Payment terms are commonly T/T in advance or LC at sight. Request a shipping manifest and container inspection report if importing in bulk.
Upon receipt, conduct a visual inspection for moisture damage or discoloration. Test a sample for moisture content using Karl Fischer titration and verify purity with HPLC against a reference standard. Retain a sample for 12 months for batch traceability. Request a batch-specific Certificate of Analysis with lot number, expiration date, and signature from the quality control manager. Document all inspection results for regulatory compliance.
