Chemical Structure

rac-[(2R,3S)-2-(1-ethyl-1H-pyrazol-5-yl)oxan-3-yl]methanol CAS 1969287-74-8 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 rac-[(2R,3S)-2-(1-ethyl-1H-pyrazol-5-yl)oxan-3-yl]methanol.

rac-[(2R,3S)-2-(1-ethyl-1H-pyrazol-5-yl)oxan-3-yl]methanol (CAS 1969287-74-8) is a high-purity analytical reference standard with the molecular formula C11H18N2O2 and a molecular weight of 210.27 g/mol.

The molecular framework of rac-[(2R,3S)-2-(1-ethyl-1H-pyrazol-5-yl)oxan-3-yl]methanol (C11H18N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), rac-[(2R,3S)-2-(1-ethyl-1H-pyrazol-5-yl)oxan-3-yl]methanol 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.
