Structure of Methyl 4-bromo-2,5-dimethylpyrazole-3-carboxylate, CAS 660408-08-2 — Structure · C7H9BrN2O2

Standard packing: 1kg / 25kg / 100kg

CAS 660408-08-2, Methyl 4-bromo-2,5-dimethylpyrazole-3-carboxylate, is a C7H9BrN2O2 heterocycle supplied in kilogram lots, stock or made to order.

Heterocycles of this substitution pattern are carried through several steps, which makes residual metal content of the lot the number that decides whether the step works. The methyl branch at C5 changes how the chain packs, which shows up in melting behaviour and in the solubility of the free material.

The formula C7H9BrN2O2 resolves to 7 carbons with 2 oxygens, 2 nitrogens and one bromine. At 7 carbons the entry is an oil or a low-melting solid, and it is handled at ambient temperature in most steps.

Handling and storage

Store closed, dry and dark. Ring oxidation and discolouration are the usual signs that a lot has been open too long.

Ordering

Standard packing 1kg / 25kg / 100kg. Other unit weights are quoted per lot and confirmed in writing before the material is packed. Nothing on this page should be read as a guaranteed minimum. The number that applies is the one on the certificate for the lot you receive.
