Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 68951-96-2 (3.0-3.5% Diphenylsiloxane)-dimethylsiloxane copolymer, vinyl terminated MFCD00240056 Siloxanes and silicones, dimethyl, diphenyl, (vinyloxy) terminated Siloxanes and silicones, dimethyl, diphenyl, vinyl terminated.

68951-96-2 (3.0-3.5% Diphenylsiloxane)-dimethylsiloxane copolymer, vinyl terminated MFCD00240056 Siloxanes and silicones, dimethyl, diphenyl, (vinyloxy) terminated Siloxanes and silicones, dimethyl, diphenyl, vinyl terminated (CAS 68951-96-2) is a high-purity analytical reference standard with the molecular formula C12H22OSiC4H10OSiC2H6OSi and a molecular weight of 386.75 g/mol.

The molecular framework of 68951-96-2 (3.0-3.5% Diphenylsiloxane)-dimethylsiloxane copolymer, vinyl terminated MFCD00240056 Siloxanes and silicones, dimethyl, diphenyl, (vinyloxy) terminated Siloxanes and silicones, dimethyl, diphenyl, vinyl terminated (C12H22OSiC4H10OSiC2H6OSi) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 68951-96-2 (3.0-3.5% Diphenylsiloxane)-dimethylsiloxane copolymer, vinyl terminated MFCD00240056 Siloxanes and silicones, dimethyl, diphenyl, (vinyloxy) terminated Siloxanes and silicones, dimethyl, diphenyl, vinyl terminated meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
