从Pakistan供应商批发进口3-Bromopropionic Acid — FOB条款

3-bromopropionic acid (CAS 590-92-1) is an alpha,beta-unsaturated bromo-carboxylic acid with molecular formula C3H5BrO2 and molecular weight of 152.98 g/mol, functioning as a versatile alkylating agent and synthetic intermediate in pharmaceutical and polymer chemistry. The compound features a terminal bromine on a three-carbon chain adjacent to a carboxylic acid group, enabling facile nucleophilic substitution at the bromomethyl terminus while retaining acidic functionality for amide or ester formation. I & K Enterprises, based in Lahore's New Muslim Town area, lists this material for export from Pakistan, positioning it within South Asia's growing speciality chemical supply sector.

The material is typically supplied as a colourless to pale yellow liquid or low-melting crystalline solid with a characteristic acidic odour, though the exact physical form and colour specification from I & K Enterprises should be confirmed directly. Industrial grades of 3-bromopropionic acid commonly assay at 97-99% purity by titration or GC-FID, with typical impurities including unreacted acrylic acid, hydrogen bromide, and propionic acid from the hydrobromination manufacturing route. Moisture content is critical for stability, as the alpha-bromo acid is prone to hydrolysis and elimination, with standard specifications typically requiring less than 0.5% water and storage under nitrogen to prevent colour development and decomposition.

This brominated acid finds application in the synthesis of beta-substituted propionic acids via nucleophilic substitution, in the preparation of thiol-reactive crosslinkers for protein modification, and as a precursor to 3-mercaptopropionic acid derivatives used in polymer stabilisers and epoxy curing agents. Pharmaceutical manufacturers utilise it for introducing three-carbon spacer arms in prodrug design, while research institutions employ it in peptide chemistry and surface functionalisation protocols. Buyers engaging I & K Enterprises should confirm the supplier's capability to provide material with specified purity, packaging suitable for international chemical transport, and any available analytical documentation, as the listing provides minimal technical detail beyond payment and contact terms.

I & K Enterprises operates from 158-a, New Muslim Town in Lahore, Punjab Province, 54000, Pakistan, a city that serves as a significant chemicals trading and light manufacturing hub with access to Karachi Port for international shipments. The supplier holds a Harbor trust tier on the platform, which represents an entry-level verification status, and displays a 0.00% response rate with no recorded average response hours, indicating that platform-based enquiry may not yield timely communication. This profile characteristic suggests buyers should establish direct contact channels, potentially through Pakistani chemical trade associations or the Lahore Chamber of Commerce, to ensure reliable communication given the limited digital responsiveness.

The listing for I & K Enterprises contains minimal corporate information, with no stated manufacturing capacity, quality management certification, years in operation, or specific industry focus beyond general chemical trading. The supplier's product description emphasises payment terms (T/T or wire transfer upfront against proforma invoice) and invites buyers to request quotation for quantity, quality, and delivery parameters, which positions I & K Enterprises as a responsive trader rather than a disclosed manufacturer. Buyers must independently verify whether the enterprise holds import/export licence from the Trade Development Authority of Pakistan, whether they source 3-bromopropionic acid from domestic producers or import for re-export, and what quality assurance protocols they apply before shipment from Lahore.
