3,5-Dimethylpyrazole
Royalchem manufactures and supplies 3,5-Dimethylpyrazole (3,5-DMP, CAS 67-51-6) through partner factories under contract manufacturing arrangements. It is used to prepare blocked-isocyanate crosslinkers for heat-cured coatings. A previously supplied 25 kg drum grade provides the reference specification shown below: assay ≥99.5% by HPLC, moisture ≤0.5% and melting range 106–108°C. Confirm the selected grade and acceptance limits for the order. The raw material melting range is distinct from formulation deblocking or curing temperature.
