3-Methyl-1-phenyl-1,4-dihydrochromeno[4,3-c]pyrazole CAS 77479-33-5

Description

The occurrence of 3-Methyl-1-phenyl-1,4-dihydrochromeno[4,3-c]pyrazole is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Methyl-1-phenyl-1,4-dihydrochromeno[4,3-c]pyrazole (CAS 77479-33-5), molecular formula C17H14N2O and molecular weight 262.31 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-Methyl-1-phenyl-1,4-dihydrochromeno[4,3-c]pyrazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 262.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
