ChlorMequat Chloride Precursor Acid from China
While primarily known as mecoprop, this 2-Methyl-4-chlorophenoxyacetic acid also serves as a precursor in synthesizing plant growth regulators, classified under HTS 2918.99.2015 for its pesticide-related aromatic carboxylic acid structure. It exhibits auxin-like activity inhibiting grass growth.
