Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methyl-2-(2-(6-chloro-3-methyl-2(3H)-benzoxazolinylidene)-1-propenyl)-3-phenylthiazoliniumiodide.
4-Methyl-2-(2-(6-chloro-3-methyl-2(3H)-benzoxazolinylidene)-1-propenyl)-3-phenylthiazoliniumiodide (CAS 31580-45-7) is a high-purity analytical reference standard with the molecular formula C22H20ClN2OSI and a molecular weight of 522.82 g/mol.
4-Methyl-2-(2-(6-chloro-3-methyl-2(3H)-benzoxazolinylidene)-1-propenyl)-3-phenylthiazoliniumiodide (C22H20ClN2OSI) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
