Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including NSP-SA-NHS, 97%.
NSP-SA-NHS, 97% (CAS 199293-83-9) is a high-purity analytical reference standard with the molecular formula C32H31N3O10S2 and a molecular weight of 681.73 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, NSP-SA-NHS, 97% is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 681.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures NSP-SA-NHS, 97% 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.
