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 (2,7-Di-tert-butyl-9H-fluoren-9-yl)methyl carbonochloridate.
(2,7-Di-tert-butyl-9H-fluoren-9-yl)methyl carbonochloridate (CAS 287381-46-8) is a high-purity analytical reference standard with the molecular formula C23H27ClO2 and a molecular weight of 370.91 g/mol.
Structurally, (2,7-Di-tert-butyl-9H-fluoren-9-yl)methyl carbonochloridate (C23H27ClO2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 370.91 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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 (2,7-Di-tert-butyl-9H-fluoren-9-yl)methyl carbonochloridate 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.
