It is also sold as (4-Methylbenzothiazol-2-yl)hydrazine, 2-Hydrazinyl-4-methyl-1,3-benzothiazole, Tricyclazole hydrazine intermediate. All refer to CAS 20174-68-9. Confirm the CAS number with any supplier before ordering.
Price depends on grade, volume, packing, Incoterm and destination port, and moves with raw material markets. Send us your requirement and we will quote in EUR or USD with a landed-cost breakdown, usually within one business day.
2-Hydrazino-4-Methylbenzothiazole (CAS 20174-68-9) is a crystalline heterocyclic hydrazine used as the key intermediate for the rice-blast fungicide tricyclazole and as a building block for fused benzothiazole systems.
Standard grade offers 98% minimum HPLC purity. Premium grade offers 99% minimum, lower moisture and inert-gas blanketed packaging. Premium is recommended for cyclisation routes with tight impurity control.
It is a direct precursor. Cyclisation of the hydrazine onto the benzothiazole ring builds the fused triazole system found in tricyclazole. Order by CAS (20174-68-9) and tell us your target route so we can match the impurity profile.
Hydrazine derivatives can face REACH, CLP and workplace-exposure obligations depending on use. We confirm the current status for your application before quoting.
Store in closed containers in a cool, dry, ventilated place, protected from light, strong oxidisers and acids. Use within the shelf life stated on the COA and TDS.
It is treated as a dangerous good (class and UN number per SDS; always confirm on the current SDS). We pack it in UN-approved containers, apply CLP labels and ship through licensed forwarders under IMDG for sea and ADR for European road.
Yes. Laboratory and pilot samples are supplied with a COA and SDS so your team can qualify the grade. Mention sample needs in your enquiry.
REACH status is confirmed before we quote. We advise on importer-of-record arrangements and whether the substance is registered for your use. Send your use descriptor and we will confirm.
