For any chemist engaged in organic synthesis, understanding and utilizing key reagents is crucial. Thionyl chloride (SOCl2), with CAS number 7719-09-7, stands out as a remarkably versatile and powerful tool in the organic synthesis toolkit. Its ability to efficiently convert carboxylic acids into acyl chlorides is a fundamental transformation that opens doors to a vast array of further reactions. The high purity, often 99.5% or greater, ensures predictable and reproducible results, which are critical for successful synthesis projects.

The reactivity of Thionyl Chloride stems from its electrophilic sulfur atom, which readily reacts with nucleophiles like the hydroxyl group of carboxylic acids. The byproducts of this reaction, sulfur dioxide (SO2) and hydrogen chloride (HCl), are gaseous, simplifying the isolation of the desired acyl chloride product. This characteristic makes SOCl2 a preferred reagent over other chlorinating agents that might produce more difficult-to-remove byproducts. When considering the purchase of SOCl2, sourcing from reliable suppliers in China offers a cost-effective option without compromising on quality.

For those looking to buy Thionyl Chloride, especially at a good price from China manufacturers, NINGBO INNO PHARMCHEM CO.,LTD. provides a dependable source. Its application extends beyond mere chlorination; acyl chlorides derived from SOCl2 are themselves highly reactive intermediates, readily converted into esters, amides, and other valuable organic compounds. Mastering the use of Thionyl Chloride is therefore a key skill for advancing complex organic synthesis, enabling the efficient creation of intricate molecular structures for various applications.
