Chemical Structure

(1-methyl-1H-1,2,4-triazol-5-yl)methanol hydrobromide CAS 1803601-43-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(1-methyl-1H-1,2,4-triazol-5-yl)methanol hydrobromide (CAS 1803601-43-5), molecular formula C4H7N3OHBr and molecular weight 194.03 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1-methyl-1H-1,2,4-triazol-5-yl)methanol hydrobromide (C4H7N3OHBr) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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.

As a certified reference material (CRM), (1-methyl-1H-1,2,4-triazol-5-yl)methanol hydrobromide 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.
