Description

CATO supplies 679818-59-8 M95KG522R0 Ofatumumab [USAN:INN:BAN:JAN] Immunoglobulin G1, anti-(human CD20 (antigen))(human monoclonal HuMax-CD20 heavy chain), disulfide with human monoclonal HuMax-CD20 kappa-chain, dimer Ofatumumab HuMax-CD20 GSK1841157 GSK 1841157 UNII-M95KG522R0 Arzerra HuMax-CD20, 2F2 Arzerra Injection HSDB 8170 (CAS 679818-59-8), a certified reference material (molecular formula C12H10N4O2, MW 242.23 g/mol) for analytical method development and quality control.

679818-59-8 M95KG522R0 Ofatumumab [USAN:INN:BAN:JAN] Immunoglobulin G1, anti-(human CD20 (antigen))(human monoclonal HuMax-CD20 heavy chain), disulfide with human monoclonal HuMax-CD20 kappa-chain, dimer Ofatumumab HuMax-CD20 GSK1841157 GSK 1841157 UNII-M95KG522R0 Arzerra HuMax-CD20, 2F2 Arzerra Injection HSDB 8170 (C12H10N4O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

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

As a certified reference material (CRM), 679818-59-8 M95KG522R0 Ofatumumab [USAN:INN:BAN:JAN] Immunoglobulin G1, anti-(human CD20 (antigen))(human monoclonal HuMax-CD20 heavy chain), disulfide with human monoclonal HuMax-CD20 kappa-chain, dimer Ofatumumab HuMax-CD20 GSK1841157 GSK 1841157 UNII-M95KG522R0 Arzerra HuMax-CD20, 2F2 Arzerra Injection HSDB 8170 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.
