Compared with other compounds in its class, the molecular weight of 222.32 g/mol gives Thioctic acid Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Thioctic acid Impurity 20 (CAS 2114407-83-7) is a certified pharmaceutical impurity reference standard with the molecular formula C8H14O3S2 and a molecular weight of 222.32 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Thioctic acid Impurity 20 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Thioctic acid Impurity 20 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.
