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 Di-p-tert-Butylphenyl Phosphorochloridate.
Di-p-tert-Butylphenyl Phosphorochloridate (CAS 38135-31-8) is a high-purity analytical reference standard with the molecular formula C20H26ClO3P and a molecular weight of 380.85 g/mol.
Di-p-tert-Butylphenyl Phosphorochloridate (C20H26ClO3P) contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Di-p-tert-Butylphenyl Phosphorochloridate 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.
