Phenyl (4,6-dimethoxy-2-pyrimidinyl)carbamate

Phenyl (4,6-dimethoxy-2-pyrimidinyl)carbamate (CAS 89392-03-0) is a pyrimidine-based carbamate compound used primarily as a chemical intermediate in agrochemical and pharmaceutical synthesis. Its reactive carbamate moiety makes it a key building block for the production of sulfonylurea and related herbicide active ingredients. In agrochemical manufacturing, it serves as a core intermediate.

It is used in the synthesis of sulfonylurea herbicides, which target acetolactate synthase in broadleaf weeds and grasses. This is a widely commercialized mode of action across cereal and rice crop protection products. Pharmaceutical producers use it as a synthetic precursor where controlled introduction of the dimethoxypyrimidine scaffold is required in drug candidate development. It is essential for specific drug sequences.

Contract manufacturers and toll synthesizers source it for multi-step API intermediate sequences requiring a stable, isolable carbamate transfer agent. Its reactivity profile also suits research-scale synthesis programs. It is frequently used for evaluating novel heterocyclic compounds for biological screening. Phenyl (4,6-dimethoxy-2-pyrimidinyl)carbamate is typically supplied as a solid powder or crystalline material.

It is available in technical grade for agrochemical intermediate use, with higher-purity specifications offered for pharmaceutical and research applications. Packaging ranges from laboratory quantities to bulk volumes.
