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

3-Chlorobenzoic acid is a halogenated aromatic carboxylic acid with molecular formula C7H5ClO2, supplied by I & K Enterprises from Lahore, Pakistan. The compound features a chlorine substituent at the meta position relative to the carboxylic acid group, conferring distinct electronic properties for synthetic applications. The source description provides no stated purity, assay method, or grade designation, so buyers must request these directly from the supplier. This chemical serves as a fundamental building block in organic synthesis, with the meta-substitution pattern enabling regioselective reactions unavailable with ortho or para isomers.

Industrial production typically proceeds via diazotization of 3-chloroaniline followed by Sandmeyer-type carboxylation, or through direct chlorination of benzoic acid with catalyst-directed meta selectivity. Standard commercial grades range from 98-99.5% purity, with pharmaceutical grade demanding tighter limits on isomeric impurities (2-chlorobenzoic and 4-chlorobenzoic acids) and trace aniline-derived compounds. The acid dissociation constant (pKa) is approximately 3.46, reflecting the electron-withdrawing chlorine influence. Typical physical form is white to pale yellow crystalline powder with characteristic aromatic odor, melting point 154-158°C depending on purity and polymorphic form. I & K Enterprises has not specified their manufacturing route, quality control protocols, or whether they source from domestic manufacturers or import for resale.

Primary buyers include pharmaceutical intermediate manufacturers requiring meta-substituted benzoic acid for NSAID synthesis, dye and pigment producers, and agrochemical formulators. The compound finds use in Coumarin-3-carboxylic acid synthesis, as a photoinitiator component, and in metal complexation studies. I & K Enterprises indicates capability for both regular and bulk orders, with telegraphic transfer payment upfront against proforma invoice. No pricing, MOQ, lead time, or delivery terms are stated in the source data. Buyers should negotiate Incoterms, likely FOB Karachi or Lahore air freight, and confirm whether the supplier provides export documentation including certificate of origin and customs clearance support.

I & K Enterprises is located at 158-a, New Muslim Town, Lahore 54000, Punjab, Pakistan. The supplier holds a 'harbor' trust tier, indicating basic platform verification without extensive third-party auditing. The response rate is 0.00% with zero average response hours, suggesting limited engagement through automated inquiry channels. Buyers should establish direct contact via the Lahore address or known Pakistani chemical trade networks. The company appears to operate as a trading enterprise rather than a manufacturer, based on the generic product description and emphasis on sourcing flexibility rather than production capacity.

No information is provided about manufacturing facilities, reactor scale, in-house analytical capabilities, or quality management system certification. The business model indicated is responsive to both regular and bulk demand, with upfront payment terms. There is no stated year of establishment, employee count, revenue figures, or client references in the source data. What can be confirmed is geographic location in Lahore, a city with established chemical trading infrastructure and access to Karachi port for international shipment. Buyers requiring vendor qualification documents, insurance certificates, or bank references should request these directly from I & K Enterprises.
