Import 3-Morpholinopropanesulfonic Acid — Buy in wholesale FOB from Supplier in China

3-Morpholinopropanesulfonic Acid (MOPS, CAS 1132-61-2, C7H15NO4S) is a morpholine-derived sulfonic acid buffer manufactured by Hubei New Desheng Materials Technology Co., Ltd. in Hubei Province, China. The compound carries a pKa of 7.2 and maintains effective buffering capacity across pH 6.5 to 7.9, making it suitable for physiological pH applications. The supplier offers this product in flake or powder form with stated purity of 98% or above for laboratory and commercial use. MOPS belongs to the Good's buffer family, selected for its minimal metal ion interaction and temperature-independent pKa characteristics.

The molecular structure combines a morpholine ring with a propanesulfonic acid group, conferring both zwitterionic character and high water solubility. Typical commercial grades meet analytical or reagent-grade specifications with controlled limits on heavy metals, chloride, and sulfate impurities. The standard manufacturing route involves sulfonation of morpholine derivatives under controlled conditions, followed by crystallisation and drying. Batch-to-batch consistency depends on rigorous control of starting material purity and reaction stoichiometry. Buyers should request a Certificate of Analysis (CoA) specifying actual purity, melting point, and moisture content for each lot.

Primary applications span cell culture media, protein electrophoresis, enzyme assays, and diagnostic kit formulation where pH stability is critical. Pharmaceutical researchers use MOPS in drug stability studies and formulation development. Molecular biology laboratories employ it in Northern and Western blotting protocols. Industrial buyers include biotech manufacturers, contract research organisations, and academic procurement departments. Importers should confirm packaging format (typically 25 kg drums or smaller laboratory containers), Incoterms, and whether the supplier provides stabilised formulations or anhydrous variants. The supplier's facility in Ezhou, Hubei, operates within the Gedian Development Zone.

Hubei New Desheng Materials Technology Co., Ltd. is located at 8-2-2, Union Technology Area C, Gedian Development Zone, Ezhou, Hubei Province, China, postal code 436070. The company operates from an industrial zone in central China with access to the Yangtze River logistics corridor. The supplier holds a Harbor trust tier designation on the marketplace, though the response rate is recorded at 0.00% with zero average response hours, indicating no historical response data is available through the platform. No verification of third-party certifications, ISO status, or export licence details is provided in the listing profile.

The company's materials technology focus suggests specialisation in fine chemicals and biochemical reagents, though the profile does not disclose founding year, registered capital, production capacity, or number of employees. Buyers should conduct direct due diligence including factory audit, quality management system review, and sample evaluation before committing to bulk orders. The supplier's product description emphasises MOPS for molecular biology, pharmaceutical research, and diagnostic kit manufacturing, but does not specify whether production occurs at the Ezhou address or at a separate manufacturing site.
