Chemical Structure

rac-(2R,3R)-2-[1-(3-methoxypropyl)-1H-pyrazol-5-yl]oxolane-3-carboxylic acid CAS 1909286-75-4 chemical structure

Description

The occurrence of rac-(2R,3R)-2-[1-(3-methoxypropyl)-1H-pyrazol-5-yl]oxolane-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

rac-(2R,3R)-2-[1-(3-methoxypropyl)-1H-pyrazol-5-yl]oxolane-3-carboxylic acid (CAS 1909286-75-4) is a high-purity analytical reference standard with the molecular formula C12H18N2O4 and a molecular weight of 254.28 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, rac-(2R,3R)-2-[1-(3-methoxypropyl)-1H-pyrazol-5-yl]oxolane-3-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
