Chemical Structure

(R)-1-(1H-Pyrazol-5-yl)ethan-1-ol CAS 29673-18-5 chemical structure

Description

As a certified reference material (CRM), (R)-1-(1H-Pyrazol-5-yl)ethan-1-ol 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.

(R)-1-(1H-Pyrazol-5-yl)ethan-1-ol (CAS 29673-18-5), molecular formula C5H8N2O and molecular weight 112.13 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (R)-1-(1H-Pyrazol-5-yl)ethan-1-ol (C5H8N2O) contains an amide group, a hydroxyl group, an ether linkage. 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 112.13 g/mol, it falls into the low-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.
