Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1903.05 g/mol gives Hepatitis C Virus S5A/5B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Hepatitis C Virus S5A/5B (CAS 191529-67-6) is a high-purity analytical reference standard with the molecular formula C81H119N19O30S2 and a molecular weight of 1903.05 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Hepatitis C Virus S5A/5B is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1903.05 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).
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 Hepatitis C Virus S5A/5B 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.
