Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7803-63-6 6218R7MBZB Ammonium bisulfate Ammonium hydrogensulphate Sulfuric acid, ammonium salt (1:1) Sulfuric acid, monoammonium salt EINECS 232-265-5 UNII-6218R7MBZB Ammonium hydrogen sulfate [UN2506] [Corrosive] UN2506 Ammonium hydrogen sulfate.

CATO supplies 7803-63-6 6218R7MBZB Ammonium bisulfate Ammonium hydrogensulphate Sulfuric acid, ammonium salt (1:1) Sulfuric acid, monoammonium salt EINECS 232-265-5 UNII-6218R7MBZB Ammonium hydrogen sulfate [UN2506] [Corrosive] UN2506 Ammonium hydrogen sulfate (CAS 7803-63-6), a certified reference material (molecular formula H2O4SH3N, MW 115.10 g/mol) for analytical method development and quality control.

The molecular framework of 7803-63-6 6218R7MBZB Ammonium bisulfate Ammonium hydrogensulphate Sulfuric acid, ammonium salt (1:1) Sulfuric acid, monoammonium salt EINECS 232-265-5 UNII-6218R7MBZB Ammonium hydrogen sulfate [UN2506] [Corrosive] UN2506 Ammonium hydrogen sulfate (H2O4SH3N) is characterized by a sulfone group. 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.

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.

CATO manufactures 7803-63-6 6218R7MBZB Ammonium bisulfate Ammonium hydrogensulphate Sulfuric acid, ammonium salt (1:1) Sulfuric acid, monoammonium salt EINECS 232-265-5 UNII-6218R7MBZB Ammonium hydrogen sulfate [UN2506] [Corrosive] UN2506 Ammonium hydrogen sulfate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
