3-{[1,1'-biphenyl]-4-yl}-5-methyl-1H-pyrazole CAS 478541-27-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-{[1,1'-biphenyl]-4-yl}-5-methyl-1H-pyrazole.

3-{[1,1'-biphenyl]-4-yl}-5-methyl-1H-pyrazole (CAS 478541-27-4), molecular formula C16H14N2 and molecular weight 234.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3-{[1,1'-biphenyl]-4-yl}-5-methyl-1H-pyrazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.30 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.

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), 3-{[1,1'-biphenyl]-4-yl}-5-methyl-1H-pyrazole 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.
