Bio-4-Methylbenzophenone
Overview
Bio-4-Methylbenzophenone is an organic compound derived from the benzophenone family, distinguished by a methyl group at the para position. It is synthesized through Friedel-Crafts acylation and is valued for its role as a building block in specialty chemicals. As a bio-variant, it emphasizes eco-friendly production methods, though its properties remain chemically identical to conventional 4-methylbenzophenone. The compound is gaining traction in industries prioritizing sustainable sourcing without compromising performance.
Physical and Chemical Properties
The compound exhibits typical benzophenone characteristics, including a crystalline structure and stability under normal conditions. Its UV absorption peak at 250-350 nm makes it effective for light stabilization applications. Key metrics include a low water solubility (0.01 g/L at 25°C) and moderate volatility. The melting point range ensures easy handling in solid form, while its solubility in organic solvents facilitates formulation in liquid systems.
Main Applications
In pharmaceuticals, Bio-4-Methylbenzophenone serves as an intermediate for antihistamines and sunscreens. Its UV-filtering properties are leveraged in coatings and plastics to prevent photodegradation. The fragrance industry uses it as a fixative to enhance longevity of perfumes. Emerging applications include organic electronics, where it acts as a charge transport material in photovoltaics.
Safety and Storage
While not acutely toxic, prolonged exposure may cause mild irritation. OSHA recommends gloves and goggles when handling powders. Storage requires airtight containers to prevent moisture absorption. Disposal should follow local regulations for non-halogenated organic compounds. The substance is not biodegradable; incineration with scrubbers is preferred for waste management.
B2B Procurement Guide
Buyers should prioritize suppliers with ISO 9001 certification and batch-specific COAs. Technical grades (95-98%) suffice for industrial uses, while pharmaceutical applications demand ≥99% purity. Bulk shipments (25 kg drums) typically offer 10-15% cost savings. Audit suppliers for solvent residue levels (<0.5%) and heavy metal compliance (USP/EP standards). Spot contracts are common due to stable pricing.
