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 17-(Tosyloxy)heptadecanoic acid.
17-(Tosyloxy)heptadecanoic acid (CAS 76298-42-5) is a high-purity analytical reference standard with the molecular formula C24H40O5S and a molecular weight of 440.64 g/mol.
17-(Tosyloxy)heptadecanoic acid (C24H40O5S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 17-(Tosyloxy)heptadecanoic acid 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.
