CAS 90-98-2 and 4,4′-Dichlorobenzophenone
From the beginning of AD to the middle of the 19th century, the main use of natural organic matter (such as animal and plant extracts) qualitative or quantitative analysis. From the second half of the 19th century to the 1920s, synthetic organic reagents started to be used, for example nickel, copper and molybdenum with potassium xanthate; aluminum with morin. Theoretical studies of the structure of organic reagents (such as electronic effects, steric effects, substituent effects) have led to the development of novel organic reagents such as heterocyclic azo reagents. Monochlorochromic and disazochromic acids have also been developed during this period. In the mid-1970s, adsorbents and chelating resins were rapidly developed. Since the 1980s, Chinese analytical chemists have also made achievements in the synthesis and application of asymmetric disazochromic acid reagents.
