Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 158.99 g/mol gives tert-Butyldichlorophosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-Butyldichlorophosphine (CAS 25979-07-1), molecular formula C4H9Cl2P and molecular weight 158.99 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, tert-Butyldichlorophosphine (C4H9Cl2P) contains organophosphorus functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 158.99 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 tert-Butyldichlorophosphine 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.
