Frequently Asked Questions

Q1: What is 2-(4-Phenylbenzoyl) Benzoic Acid (4BB) and what is it used for?

A1: It is a specialty benzoic acid derivative (C20H14O3, mol. wt. 302.32, CAS 42797-18-2) used as an industrial fine chemical raw material in resin and polymer applications. It's a key intermediate for producing benzophenone-based photoinitiators and specialty polymer monomers.

Q2: What purity and impurity specifications does 4BB need to meet for polymer/resin applications?

A2: It must meet HPLC purity of NLT 99.0%, moisture NMT 0.50%, iron content NMT 25 ppm, residual aluminium NMT 800 ppm, residual biphenyl NMT 250 ppm, and residual chlorobenzene and other non-chlorinated organic solvents each NMT 1000 ppm — reflecting the stringent metal and solvent control needed in high-performance resin systems.

Q3: Why are residual metal impurities (iron and aluminium) specifically controlled in 4BB?

A3: Metal impurities like iron and aluminium can catalyse side reactions, affect polymerization kinetics, or cause discolouration in final resin products. Controlling them to PPM levels ensures consistent, high-quality output in photoinitiator and polymer synthesis.

Q4: How is 4BB packaged for large-volume supply, and what is its shelf life?

A4: It's packed in 500 kg net jumbo bags (1 bag per pallet), with a 20-foot container holding 5,000 kg and a 40-foot container holding 10,000 kg. Shelf life is not specified on the page but standard ambient storage in a closed container away from direct sunlight is recommended.

Q5: Does Sarex manufacture and export 4BB for global photoinitiator and resin producers?

A5: Yes, Sarex is a leading fine chemical manufacturer and exporter in India, producing 4BB at 60 MT annual capacity and supplying it to resin, polymer, and photoinitiator producers in more than 40 countries.
