Chemical Structure

Ethyl 5-chloro-4-iodo-1H-pyrazole-3-carboxylate CAS 1934360-92-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 300.48 g/mol gives Ethyl 5-chloro-4-iodo-1H-pyrazole-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 5-chloro-4-iodo-1H-pyrazole-3-carboxylate (CAS 1934360-92-5), a certified reference material (molecular formula C6H6ClIN2O2, MW 300.48 g/mol) for analytical method development and quality control.

Structurally, Ethyl 5-chloro-4-iodo-1H-pyrazole-3-carboxylate (C6H6ClIN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 300.48 g/mol, it falls into the moderately-high-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.

As a certified reference material (CRM), Ethyl 5-chloro-4-iodo-1H-pyrazole-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
