Import 3-Morpholinopropane Sulfonic Acid Mops — Buy in wholesale FOB from Supplier in China

3-Morpholinopropane sulfonic acid, abbreviated MOPS, is a zwitterionic biological buffer with CAS number 1132-61-2 and molecular formula C7H15NO4S, supplied by Hubei Desheng Material Technology Co., Ltd from Ezhou City, Hubei Province, China. The compound has a molecular weight of 209.26 g/mol and is offered at 99% purity as a pure white crystalline powder with good water solubility. MOPS is used primarily in biochemistry and molecular biology for maintaining stable pH in cell culture media, protein electrophoresis, and particularly in RNA electrophoresis buffers where its low UV absorbance and minimal metal chelation are advantageous.

The morpholine ring with a propane sulfonic acid side chain gives MOPS a pKa of 7.20 at 25 °C, making it effective for buffering in the pH 6.5-7.9 range. The 99% purity grade from Hubei Desheng is suitable for most research and diagnostic applications, though pharmaceutical or cell therapy-grade applications may require further endotoxin and bioburden testing that the listing does not specify. Standard storage is at room temperature protected from light and moisture, with typical shelf life of 36 months when properly sealed. The material is non-hazardous for transport, simplifying logistics compared to regulated chemicals.

Buyers include university research laboratories, in vitro diagnostics manufacturers formulating reagent kits, biopharmaceutical companies developing cell culture processes, and contract research organisations running RNA and protein assays. Hubei Desheng's location in Ezhou, near Wuhan, provides access to the Yangtze River port network and Wuhan Tianhe International Airport for expedited air freight. Importers should confirm with Desheng whether the 99% purity refers to titration assay, HPLC area%, or another analytical method, and whether the supplier provides lot-specific COAs with moisture and solubility data. The company does not state MOQ, lead time, or export packaging configurations in the listing.

Hubei Desheng Material Technology Co., Ltd is located at Gaoxin 3rd Road, Huarong District, Ezhou City, Hubei Province, China (postal code 436000). The company holds a harbor trust tier. No response rate or average response time statistics are available. The listing describes Desheng as a supplier of biological buffers with particular emphasis on MOPS production. The profile does not state the year of establishment, number of employees, annual production capacity, or whether the company manufactures MOPS in-house or sources from a contracted facility.

The available information indicates that Hubei Desheng markets MOPS at 99% purity with emphasis on stable process control to achieve consistent white crystalline appearance. No certifications such as ISO 9001, ISO 13485, or GMP are mentioned. Buyers should request business licence verification, production facility audit reports, and references from existing buffer customers. Ezhou's proximity to Wuhan provides logistical advantages for both domestic and export shipping, though buyers need to confirm Desheng's experience with international documentation, customs classification (typically HS 2922.19 or 2934.99 depending on jurisdiction), and whether they have handled EU or US pharmaceutical customer shipments previously.
