Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-N,N-dimethylpyrazole-1-sulfonamide.
5-Chloro-N,N-dimethylpyrazole-1-sulfonamide (CAS 769937-44-2), molecular formula C5H8ClN3O2S and molecular weight 209.65 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Chloro-N,N-dimethylpyrazole-1-sulfonamide (C5H8ClN3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 209.65 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
