Ethyl 3-amino-1H-1,2,4-triazole-1-carboxylate CAS 41995-94-2

Description

As a certified reference material (CRM), Ethyl 3-amino-1H-1,2,4-triazole-1-carboxylate 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.

Ethyl 3-amino-1H-1,2,4-triazole-1-carboxylate (CAS 41995-94-2), molecular formula C15H14Cl2N2O3 and molecular weight 341.19 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 3-amino-1H-1,2,4-triazole-1-carboxylate (C15H14Cl2N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
