Structure of 4-Bromo-1,3-dimethyl-1H-pyrazole-5-carboxylic acid, CAS 5775-88-2 — Structure · C6H7BrN2O2

CAS number: 5775-88-2
Molecular formula: C₆H₇BrN₂O₂
Molecular weight: 219.04 g/mol
Standard packing: 1kg / 25kg / 100kg

CAS 5775-88-2, 4-Bromo-1,3-dimethyl-1H-pyrazole-5-carboxylic acid, is a C6H7BrN2O2 acid supplied in kilogram lots with a batch COA.

Acids of this size usually sit at the end of a route, so the release specification and the packing matter more to the buyer than the reactivity does. The methyl branch at C3 changes how the chain packs, which shows up in melting behaviour and in the solubility of the free material.

The formula C6H7BrN2O2 resolves to 6 carbons with 2 oxygens, 2 nitrogens and one bromine. With 6 carbons the molecule is small enough to be lost to evaporation during a work-up, so the step is usually run closed.

Handling and storage

Keep the container sealed and separate from amines: salt formation on the outside of a badly stored drum is a real handling problem.

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.
