Chemical Structure
Description
As a certified reference material (CRM), 4-Aminoisoxazole Hydrochloride 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.
4-Aminoisoxazole Hydrochloride (CAS 108511-98-4) is a high-purity analytical reference standard with the molecular formula C3H4N2OHCl and a molecular weight of 120.54 g/mol.
The molecular framework of 4-Aminoisoxazole Hydrochloride (C3H4N2OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
