Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3,5,7,9,11,13,15-Heptaisobutylpentacyclo[9.5.13,9.15,15.17,13]octasiloxan-1-yl)propylmethacrylate 307531-94-8 PSS-(1-Propylmethacrylate)-Heptaisobutyl substituted.

3-(3,5,7,9,11,13,15-Heptaisobutylpentacyclo[9.5.13,9.15,15.17,13]octasiloxan-1-yl)propylmethacrylate 307531-94-8 PSS-(1-Propylmethacrylate)-Heptaisobutyl substituted (CAS 307531-94-8) is a high-purity analytical reference standard with the molecular formula C35H74O14Si8 and a molecular weight of 943.64 g/mol.

3-(3,5,7,9,11,13,15-Heptaisobutylpentacyclo[9.5.13,9.15,15.17,13]octasiloxan-1-yl)propylmethacrylate 307531-94-8 PSS-(1-Propylmethacrylate)-Heptaisobutyl substituted (C35H74O14Si8) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
