Description
As a certified reference material (CRM), 1,3-Dimethyl-1H-pyrazole-4-carboxylic acid hydrochloride 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.
1,3-Dimethyl-1H-pyrazole-4-carboxylic acid hydrochloride (CAS 1185293-73-5) is a high-purity analytical reference standard with the molecular formula C6H8N2O2HCl and a molecular weight of 176.60 g/mol.
Structurally, 1,3-Dimethyl-1H-pyrazole-4-carboxylic acid hydrochloride (C6H8N2O2HCl) contains an amide 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 176.60 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.
