Description

Compared with other compounds in its class, the molecular weight of 176.18 g/mol gives 157124-41-9 4-(5-Methyl-1H-tetrazol-1-yl)phenol 4943AD C8H8N4O distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

157124-41-9 4-(5-Methyl-1H-tetrazol-1-yl)phenol 4943AD C8H8N4O (CAS 157124-41-9), molecular formula C8H8N4O and molecular weight 176.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 157124-41-9 4-(5-Methyl-1H-tetrazol-1-yl)phenol 4943AD C8H8N4O (C8H8N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
