CAS 74222-95-0 | Methyl 2-isocyanatosulfonylbenzoate

Properties:

Appearance: Colorless to pale yellow liquid at room temperature
Density: 1.38 ± 0.1 g/cm ³ 
Boiling point: 150 ° C
Flash point: 172.7 ° C
Refractive index: 1.57

Application:

As an intermediate of sulfonylurea herbicides (BIM intermediate)
1. Pesticide field
Used for synthesizing sulfometuron methyl: condensed with 4-methyl-5-propoxy-2,4-dihydro-3H-1,2,4-triazole-3-one (PMT) to prepare the herbicide for wheat grass family weeds.
Related herbicides include: sulfometuron methyl, sulfometuron methyl, sulfometuron methyl, and sulfometuron methyl
Mechanism of action: Through highly selective addition of isocyanate (- NCO) and amino (- NH2), a sulfonylurea (- SO2-NH-CO-NH -) active structure is formed, which inhibits weed acetyl lactate synthase (ALS).
2. Pharmaceuticals and Fine Chemicals
Pharmaceutical intermediates: used for synthesizing drug molecules containing sulfonamide and urea based structures (such as diuretics, hypoglycemic drugs, kinase inhibitors).
