Methyl 2-benzoylbenzoate 606-28-0
Category : Paint and Coatings/Inks and Printing Oil
CAS NO : 606-28-0 EC NO : 210-112-3 MF : C15H12O3 MW : 240.26 Specification : 99% min Packing : 25kg 50kg drum or bag Product description : What is the chemical of Methyl 2-benzoylbenzoate ? Appearance:white to light yellow crystal powder Assay: 99% min by HPLC IR Identity: conform to standard HNMR： conform to standard carbon spectrum: conform to standard Water by K. F.:0.5% max or as per the customer’s request Loss on drying:0.5% max. or as per the customer’s request ============================================================================== Main uses: Used as a photoinitiator for UV curing coatings and inks (such as photoinitiator OMBB), and also serves as an anti UV absorber. It has been used in food packaging materials (but not directly as a food preservative, which is often a misconception or confusion); Widely used in industry for offset/flexographic/screen printing inks, wood coatings, adhesives, and electronic coatings. =============================================================================== Typical synthesis route: Obtained by esterification of ortho benzoyl benzoic acid (CAS 85-52-9) with methanol under acid catalysis; In industry, phthalic anhydride can also undergo Friedel Crafts acylation with benzene to produce phthalic anhydride, which is then esterified (commonly activated by SOCl ₂ or directly catalyzed by acid); There are also literature reports on the use of pathways such as the reaction of 2-benzoylbenzoyl chloride with sodium methoxide (approximately 19 known pathways, but esterification is the most commonly used) Uses : UV absorber: used for food and beverage preservation and UV-curable coatings Photoinitiator: used in UV-curable coatings and inks Synonyms : Methyl 2-Benzoyl Benzoate;2-Benzoylbenzoic acid methyl ester;OMBB;Methyl-O-benzoyl benzoate;Photoinitiator-MBB;methyl o-benzoyl benzoate;OBM;2-Benzoyl Benzomethoxycarbonyl;o-Methyl-benzoyl Benzoate; Molecular Structure :
