2-Methyl-2,4,6,7-tetrahydropyrano[4,3-c]pyrazole-3-carboxylic acid CAS 1519903-75-3 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 2-Methyl-2,4,6,7-tetrahydropyrano[4,3-c]pyrazole-3-carboxylic acid.

2-Methyl-2,4,6,7-tetrahydropyrano[4,3-c]pyrazole-3-carboxylic acid (CAS 1519903-75-3) is a high-purity analytical reference standard with the molecular formula C8H10N2O3 and a molecular weight of 182.18 g/mol.

Structurally, 2-Methyl-2,4,6,7-tetrahydropyrano[4,3-c]pyrazole-3-carboxylic acid (C8H10N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 182.18 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).
