Benzophenone

Benzophenone, with the molecular formula C13H10O, is an aromatic ketone widely employed as a photoinitiator in ultraviolet-curable coatings, inks, and adhesives, and as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and polymer additives. I & K Enterprises, based in Lahore, Pakistan, offers this material with trade terms centered on T/T or bank/wire transfer upfront against proforma invoice. The compound features a carbonyl group flanked by two phenyl rings, absorbing UV light in the 250-360 nm range with a peak near 330 nm in ethanol solution. This absorption profile makes it effective for initiating free-radical polymerization of acrylate and methacrylate monomers in industrial coating applications.

Industrial-grade benzophenone typically presents as white or off-white crystalline flakes or powder with a characteristic sweet, floral odor and a melting point of 48-51°C. The material is produced commercially by the Friedel-Crafts acylation of benzene with benzoyl chloride using aluminum chloride catalyst, or by air oxidation of diphenylmethane. Standard purity for industrial applications ranges from 99.0% to 99.5% by gas chromatography, with critical impurities including diphenylmethane, benzhydrol, and traces of chlorinated aromatics from the manufacturing process. For photoinitiator use, the molar extinction coefficient at 330 nm and the absence of color-body impurities are key quality indicators that affect cure speed and final coating appearance.

Primary buyers of benzophenone from Pakistan include manufacturers of UV-curable wood coatings, graphic arts inks, and fiber-optic cable coatings, alongside pharmaceutical firms using it as a precursor for antihistamine and hypnotic drug synthesis. I & K Enterprises indicates capacity for regular and bulk orders, though exact minimum order quantities are not specified and require direct confirmation. The supplier's location in Lahore provides access to Pakistan's chemical trading infrastructure, with potential shipping routes through Karachi Port for international consignments. Buyers should evaluate sample material for odor, color, and melt range before committing to volume orders, as these simple tests rapidly reveal gross quality deviations without requiring laboratory analysis.

I & K Enterprises operates from 158-a, New Muslim Town, Lahore 54000, Punjab province, Pakistan. The supplier holds harbor trust tier status, indicating basic platform verification of business documentation without extended audit or third-party certification. The response rate is recorded at 0.00% with zero average response hours, suggesting that direct communication may be delayed and buyers should expect to follow up persistently on inquiries. The Lahore location positions the company within Pakistan's second-largest city and principal industrial hub, with established chemical trading networks connecting to Karachi Port for export shipments.

No information is provided regarding year of establishment, employee count, annual turnover, manufacturing capabilities, or existing client base. The listing describes payment terms and order flexibility but lacks specifics on inventory holding, quality control infrastructure, or technical staff availability. Buyers should request company registration documents, tax identification, and banking references as part of standard due diligence. For pharmaceutical-grade requirements, additional verification of GMP compliance, facility inspection reports, and regulatory approvals from the Drug Regulatory Authority of Pakistan would be necessary before qualifying I & K Enterprises as an approved supplier.
